I'm really new to setting up web servers in general. I've got IIS 8 on Windows 8, and I'm trying to set up a little site locally, while doing some development. In IIS I choose Add Site, give a name, points to a location where I have a index.html file (I've tried different locations, latest in a c:\inetpub\wwwroot\test -folder) and otherwise use all default settings. However, when I try to browse to localhost I get
HTTP Error 503. The service is unavailable.
I've verified the pool is started, and I've given IIS_IUSRS Full Control on the target folder
I've search around but not found anything that solved my issue, and there's nothing helpfull in the EventLog or in the C:\Windows\System32\LogFiles\HTTPERR folder
Could anyone tell me what's wrong?
It could be that the user identity is outdated, especially if you've tried starting a stopped app pool and the next request again fails.
In IIS, go to the Application Pools under the Server, then find the correct Application Pool for your web site, and click on it. On the Advanced Settings menu to the right, select Identity and change it and enter new user and password. Click on your Application Pool again, and select Recycle to restart it.
You can also try looking at the error message in Event Viewer, under Windows Logs, Application, Details tab.
Other answers are fine. But in my case, I was working on a Windows box that already was running some old IIS, IISExpress or any other web site. What happened is urls ACLs where reserved somehow in the system. So, you might want to check this.
Here is the console command to dump all URL acls:
netsh http show urlacl
Check what's returned here, and if anything matches the url you are testing, here is the command to delete one URL acl (for example):
netsh http delete urlacl url=http://localhost:2018/
(beware to carefully note what you do here in case it was not related to the original problem)
In my case the problem was the DefaultAppPool. I changed the "Load User Profile" to false and now it works. However, I don't know if there are side effects to this.
Further reading on setting the Load User Profile option: What exactly happens when I set LoadUserProfile of IIS pool?
Check your application's respective Application Framework Pool - it could be stopped. If it is, start it and check again.
If you're still experiencing issues you can also check out Event Viewer to find the cause of that error in order to troubleshoot more.
If the app pool is running under some specific user identity, then go to the advanced settings and update the username and password again to ensure they are correct.
If the app pool immediately stops after you start it and your event log shows:
The worker process for application pool 'APP_POOL_NAME' encountered an
error 'Cannot read configuration file ' trying to read configuration
data from file '\?\', line number '0'. The data field contains
the error code.
... you may experiencing a bug that was apparently introduced in the Windows 10 Fall Creators Update and/or .Net Framework v4.7.1. It can be resolved via the following workaround steps, which are from this answer to the related question Cannot read configuration file ' trying to read configuration data from file '\\?\<EMPTY>', line number '0'.
Go to the drive your IIS is installed on, eg. C:\inetpub\temp\appPools\
Delete the directory (or virtual directory) with the same name as your app pool.
Recycle/Start your app pool again.
I have reported this bug to Microsoft by creating the following issue on the dotnet GitHub repo: After installing 4.7.1, IIS AppPool stops with "Cannot read configuration file".
EDIT
Microsoft responded that this is a known issue with the Windows setup process for the Fall Creators Update and was documented in KB 4050891, Web applications return HTTP Error 503 and WAS event 5189 on Windows 10 Version 1709 (Fall Creators Update). That article provides the following workaround procedure, which is similar to the one above. However, note that it will recycle all app pools regardless of whether they are affected by the issue.
Open a Windows PowerShell window by using the Run as administrator
option.
Run the following commands:
Stop-Service -Force WAS
Remove-Item -Recurse -Force C:\inetpub\temp\appPools\*
Start-Service W3SVC
Or if none of the current solutions work, look in your website's directory for a file called app_offline.htm. That basically tells IIS that your site is unavailable and to show this page instead.
To fix it, either delete it or rename it to app_offline.htm.bak.
In my case, I added it while showing a colleague how to use that to prevent traffic to the site temporarily and then forgot that I did that on my box. Sigh.
Start by looking in Event Viewer, either under the System or the Application log.
In my case the problem was that no worker process could be started for the App Pool because its configuration file couldn't be read - I had included an extra '.' at the end of its name.
I resolved this issue by removing a URL reservation that matched my app directory in IIS. I had a similar (definitely not the same) issue as outlined in this article:
A Not So Common Root Cause for 503 Service Unavailable
It is possible that your domain requires the account used for running the AppPool to have batch logon rights. In which case you will see this same error message. The way you can tell if that is the case, is by looking at the System events in the Event Viewer. There should be an event saying that the account being used with the App Pool has either 'the wrong password or does not have batch logon rights'.
This is why developers quite often use IIS Express on their development machine, since it by passes the batch logon rights issue.
I ran into the same issue, but it was an issue with the actual site settings in IIS.
Select Advanced Settings... for your site/application and then look at the Enabled Protocols value. For whatever reson the value was blank for my site and caused the following error:
HTTP Error 503. The service is unavailable.
The fix was to add in http and select OK. The site was then functional again.
For my case, My Default Application Pool was offline.
To troubleshoot the problem, I checked the IIS logs located in C:\Windows\System32\LogFile\HTTPERR. Scroll down to the most recent error logs, this will show you problems with IIS if any.
My Error was "503 1 AppOffline DefaultPool"
Solution
Open IIS Manager
Click on Application Pools, this lists all application pool to your right.
Check if the application pools hosting your api or site has a stop sign on it. If so, right click the application pool and click start.
Try again to access your service from the client
Check Event Viewer - Windows - Application. If there is a red Error line made from IIS-W3SVC-WP and the message is like The Module DLL C:\Windows\system32\inetsrv\rewrite.dll failed to load. The data is the error. then you are missing some Windows Setup features.
In Windows Server 2012 go to Server Manager, Add Roles and Features, Web Server (IIS) and add the matching feature. Usually, most of the Application Development section is installed. Here is a complete list of IIS features and their associated DLL to help in diagnosis.
After going through a few iterations of that I ended on the error message above regarding "rewrite.dll". This led to a direct download and install of Microsoft URL Rewrite tool. Finally all websites came to life.
Our server ran out of disk space on Sunday afternoon which led to an application suddenly failing and returning HTTP error 502. The logs were empty so it had to be something that was occurring before IIS even did anything.
A swift look at the event viewer(WIN+R > eventvwr) exposed the issue.
It's a good idea to filter out the output of the System and Application windows to WAS since it can get pretty verbose in there.
The application depended on another one which was disabled. Therefore keep in mind an application can go down indirectly if one of it's dependent processes has gone down. We simply re-enabled the .NET application pool and our other application started running normally again.
If you have IIS URL Rewriting installed it could be to do with that. I suffered issues after a Windows 10 Update.
This StackOverflow post helped me.
Go to Windows Control Panel > Programs and Features > IIS URL Rewrite Module 2 > Repair.
i see this error after install url rewrite module i try to install previous version of it from:
https://www.microsoft.com/en-us/download/details.aspx?id=7435
it fixed my error
In my case, the problem was that another application was using the port that I had bound to my web site.
I found it by running the following command from a command line, which lists all of the listening ports and the executable involved:
netstat -b
If you have McAfee HIPS and if you see the following error in event viewer application log:
The Module DLL C:\Windows\System32\inetsrv\HipIISEngineStub.dll failed to load.
The data is the error.
Then this workaround on McAfee.com resolved the issue in my case.
Quote from the page:
Click Start, Run, type explorer and click OK.
Navigate to: %windir%\system32\inetsrv\config
Open the file applicationHost.config as Administrator for editing in Notepad.
Edit the <globalModules> section and remove the following line:
<add name="MfeEngine" image="%windir%\System32\inetsrv\HipIISEngineStub.dll" />
Edit the <modules> section and remove the following line:
<add name="MfeEngine" />
After you have finished editing the applicationHost.config file, save the file, then restart the IIS server using iisreset or by restarting the system.
Actually, in my case https://localhost was working, but http://localhost gave a HTTP 503 Internal server error. Changing the Binding of Default Web Site in IIS to use the hostname localhost instead of a blank host name.
tname for http binding
This could also happen if any recent installs or updates happened with .NET framework and/or ASP.NET. If you are unsure of what happened recently and if all your apps use ASP.NET version 4, you can try reset them by running the following commands in command prompt in administrator mode.
cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319
aspnet_regiis -i
This makes sure to install or reinstall ASP.NET 4 and updates existing applications to use ASP.NET 4 version of the app pool. It updates both IIS Classic and Integrated mode handlers and script mappings in the IIS metabase. It also recreates ASP.NET v4.0 and ASP.NET v4.0 Classic app pools, and sets .NET framework 4 to DefaultAppPool and Classic .NET app pools.
I changed the port from 80 to 8080, that's why this error occur. I write localhost/ in search bar then this error occur. My problem is resolved by writing localhost:8080/ in the search then local host open.
This happened to me on a server on our intranet. After browsing through blog posts and Windows logs, it turned out that a few days before Christmas 2015 (related to a Windows Update?) my web site application pool wanted to create a config file in folder c:\inetpub\temp\appPools, but access to this folder was restricted. This caused the application pool to be disabled.
After adding Full control to Everyone on this temp folder, I restarted the Windows Process Activation Service and everything went online again.
If I'd been a little more elegant, it would probably had been enough to grant the AppPool user full control to the folder, but I never seem to remember how the app pool name and app pool user relates to eachother...
Same thing with IIS Express 10.0 after upgrading Windows 7 to Windows 10.
Solution: go to IIS and enable all disabled websites and reinstall ASP.NET Core.
Also check the address bar and make sure the page is in the right location.
This error can be returned instead of the 404 (Page not found). In my case, it was a bad link on the page that didn't have a subfolder included.
I was having this problem when cleaning up my IIS on dev machine, and I had somehow created a virtual folder for a subfolder of my actual development web that I couldn't clear and was creating conflicts.
To clear it I had to use
C:\Windows\System32\inetsrv\appcmd.exe list vdir
and then individually remove the problem virtual directories using
C:\Windows\System32\inetsrv\appcmd.exe delete app /app.name:"Default Web Site"/{name of virtual directory}
For me the solution is to change Enable 32-bit Applications to False
None of the answers worked for me. So I'd like to share what I found after hours of research..
Keep seeing this message from event logs: The Module DLL C:\Windows\system32\RpcProxy\RpcProxy.dll failed to load. The data is the error. Turns out that dll is 64bit and cannot be loaded into 32bit process.
You can also try the following.
Right-click on the site and 'Basic Settings...'
Click on 'Connect As...'
Click on Specific User and give the new credentials.
Now it should work.
In my case, I had to change my userPass of network because company policies. So, you need to edit your AppPool:
click on Application Pools. Select your pool, 'advanced Settings...' go to 'Process Model' click on 'Identity' and Click on Specific User and give the new credentials.
This might be because of number of connections to the database. I had such a situation and so, wrote a de-constructor and killed db open connection and it resolved.
I had the same problem and found it was caused by permission problems creating the user profile in C:\Users. I gave ApplicationPoolIdentity full permissions to the C:\Users folder, started the site and everything worked, the profile must have been created properly, and my site worked as it should. I then removed access to C:\Users from ApplicationPoolIdentity.
Site wont start on local using ApplicationPoolIdentity, only when using NetworkService: "HTTP Error 503. The service is unavailable."
Hey I got problem in running .NET framework 4.0 website on IIS7.0.
the error I got is like:
HTTP Error 404.2 - Not Found "The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server".
Module : IsapiModule ,
Notification : ExecuteRequestHandler,
Handler : PageHandlerFactory-ISAPI-4.0_32bit ,
Error Code : 0x800704ec
Go to IIS manager and click on the server name. Then click on the "ISAPI and CGI Restrictions" icon under the IIS header. Change ASP.NET 4.0 from "Not Allowed" to "Allowed".
If you look in the ISAPI And CGI Restrictions, and everything is already set to Allowed, then make sure that the ASP.NET v4.0.30319 handlers are even in the list. In my case they were not. This can be easy to overlook.
I added one for 32 %windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll and another for 64 bit %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll. You can name them both the same ASP.NET v4.0.30319.
Check Allow extension path to execute.
Go to the IIS Manager.
open the server name like (PC-Name)\.
then double click on the ISAPI and CGI Restriction.
then select ASP.NET v4.0.30319(32-bit) Restriction allowed.
In my case, the problem was more severe: turns out asp.net was not correctly registered.
This response worked fine.
simply ran the following command at the command prompt
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
If I had been on a 32 bit system, it would have looked like the following:
%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i
Step 1: Open IIS and click the server name
Step 2. Double click “ISAPI and CGI Restrictions”
Step 3. Right click ASP.NET v4.0.30319 and select “allow”
After
Stopping and Starting the World Wide Web Publishing Service
1.Go to Start > All Programs > Administrative Tools > Services.
2.In the services list, right-click World Wide Web Publishing Service, and then click Stop (to stop the service), Start (to start it after it has been stopped), or Restart (to restart the service when it is running).

If you are running Delphi, or other native compiled CGI, this solution will work:
As other pointed, go to IIS manager and click on the server name. Then click on the "ISAPI and CGI Restrictions" icon under the IIS header.
If you have everything allowed, it will still not work. You need to click on "Edit Feature Settings" in Actions (on the right side), and check "Allow unspecified CGI modules", or "Allow unspecified ISAPI modules" respectively.
Click OK
In our case the solution to this problem did not involve the "ISAPI and CGI Restrictions" settings. The error started occuring after operations staff had upgraded the server to .NET 4.5 by accident, then downgraded to .NET 4.0 again. This caused some of the IIS websites to forget their respective correct application pools, and it caused some of the application pools to switch from .NET Framework 4.0 to 2.0. Changing these settings back fixed the problem.
If you look in the ISAPI And CGI Restrictions, and everything is already set to Allowed, and the ASP.NET installed is v4.0.30319, then in the right, at the "Actions" panel click in the "Edit Feature Settings..." and check both boxes. In my case, they were not.
Try changing the AppPool Manged Pipeline Mode from "Integration" to "Classic".
Depending on the type of application, another thing to check is under the Advanced Settings for the Application Pool make sure "Enable 32-Bit Applications" is set to True.
I'd checked everything in this thread when I had this issue but all had already been setup correctly, I found this was the problem for me.
If you don't have ISAPI and CGI Restrictions option listed, here is how to add it. How to add ISAPI and CGI Restrictions
After mapping of Application follow these steps
Open IIS
Click on Applications Pools
Double click on website
Change Manage pipeline mode to "classic"
click Ok.
Ow change .Net Framework Version to Lower version
Then click Ok
I have a web project which works fine on my local development machine.
I copied the project to our UAT server, setup a virtual directory pointing to the project and configured it to run on .NET Framework 4.0. I even added the Default.aspx page to the Documents tab. I configured Directory Security to use Windows Authentication.
When i try to access any web page within this application, IIS responds with a blank page. I looked through the event logs and don't see any errors anywhere.
Can someone please help me understand what's going on and how to remedy this?
Thanks in advance!
If you're just seeing a white page with no errors in the event log, it sounds like it could be a problem with the application rather than the hosting environment.
However, there are a few things you could try to doing to troubleshoot this.
Check folder permissions. Try allowing "Everyone" access on your webroot folder and see if that makes any difference.
Confirm that the IIS path is set up correctly but putting a text file in your webroot folder, and then browsing to it and verifying that it's contents are displayed.
Create a basic test.aspx page without any script, just a "Hello World" bit of text, and try browsing to it. Confirm that it displays the correct content.
Edit web.config and turn off custom errors
Try re-registering the ASP.NET extensions with IIS using aspnet_iis (details here)
Hopefully, one of these tests will be able to give you some kind of detailed error message or more insight into the cause of the problem.
For IIS 6.0 on Windows Server 2003, after the install of .NET Framework 4.0, the process of creating Web Sites or Virtual Directories that run under .NET Framework 4.0 is as follows:
Create a new application pool.
Applications running under different
frameworks can't be hosted in the
same application pool, i.e. create
an application pool perf framework.
Next, if you are creating a local
intranet site or virtual directory,
ensure that you don't have "dots" in
the application name. Browsers
confuse the dots to be external web
sites, forcing them to run under
internet zone as appose to the
intranet zone.
Once you create your web site or
virtual directory, make sure that it
runs under an application pool
dedicated for .NET 4.0 applications.
Ensure that when creating your
website or virtual directory, you
click on the ASP.NET tab and select
version 4.0 from the drop down.
Then you may configure as per
normal, with any other additional
settings you may require.
Hope this helps someone experiencing similar issues. Took a while to figure out.
I recently upgraded from XP to Win 7. I used to be able to debug from an ASP classic app into VB6. However I now get a:
"The call to Server.CreateObject failed while checking permissions. Access is denied to this object"
This only occurrs when I start the dll in VB6 and access the ASP application. Prior to IIS7 this would allow you to step into the VB6 dll. Any ideas?
I have recently had the same experience going from WinXP to Win7 in our dev environment and had have exactly the same grief with some of our legacy apps. Here's how I fixed it.
To be clear, our Classic ASP website makes calls off to our in-house VB6 .dlls and it was these .dll files that I wanted to be able to step into and debug.
Enable 32-bit applications
In the Application Pools section, right click on the website's application pool and select 'Advanced Settings'.
Change the 'Enable 32-bit Applications' to 'True'.
Change the 'Managed Pipeline Mode' to 'Classic'.
ASP Authentication
As #GregWoods has suggested, check the authentication details of the website in IIS, As follows:
Anonymous Authentication – DISABLED
ASP.Net Impersonation – DISABLED
Basic Authentication – ENABLED
Forms Authentication – DISABLED
Windows Authentication – ENABLED
Run the VB6 application inside the Visual Basic IDE and open a web browser; navigate to the website and when the code enters the external VB6 .dll, the Visual Basic 6 environment should now stop on the breakpoints set in your code. Ta da.
A step more??
I also wanted to be able to debug the actual Classic ASP pages themselves from within VS2010 or VS2012... which is entirely possible too, but there's an extra step to add to this list, simply to instruct IIS to :
In IIS, click on the website that created earlier and in the Features view, click on ‘ASP’.
Expand the ‘Debugging Properties’ option group.
Change the ‘Enable Client-side Debugging’ to ‘True’.
Change the ‘Enable Server-side Debugging’ to ‘True’.
Click ‘Apply’ to save. (Top right corner of the Actions pane).
Then, in order to make Visual Studio stop on a breakpoint, you have to Attach to Process:
Go to the 'TOOLS' menu, and select 'Attach to Process...'
Change the 'Attach to' option to 'Automatic: Native code'
Select the 'w3wp.exe' process and click 'Attach'.
Now, when you open the website in your chosen browser and nabigate to your website, IIS and VS2010/VS2012 will work in conjunction and Visual Studio will stop on any break points.
Hope this helps you.
I've just run into the same problem, and after applying the above 'fixes', still had a problem. I found that making sure that the web application has Anonymous authentication turned off (I used Windows authentication instead) finally allowed me to debug vb6 from classic ASP.
From this I cannot whether the registry entry, or the DCOM permissions change (both from q259725), contributed to the fix.
Hope this helps someone!
I'm trying to get Cruisecontrol.NET running with Server 2008/IIS7 and when I try and navigate to the dashboard I get the following error:
HTTP Error 404.17 - Not Found
The requested content appears to be script and will not be served by the static file handler.
I'm a bit lost in IIS7 so it could be something pretty straightforward. They (cc.net) do some funny stuff with http handlers in the web.config which may be related to the problem:
Anyone have any pointers?
Is the dashboard set up as an application in IIS?
I've not used IIS7, but I know in IIS6 you need to enable an application and assign it to an app pool before you can run ASPX code.
EDIT: This works in IIS6.
Open the IISAdmin tool on the web server. Expand the web sites folder. Find the virtual directory (directories?) for CruiseControl. Right-click on it and look at properties. On the directory tab, create a new application and give it a suitable name. Enable the application to execute "scripts only". Assign it to an application pool (you may want to create a new one just for this application -- consult the help documentation for this). You may also need to change the ASP.NET version You can do this on the ASP.NET tab -- choose either v1.1 or v2.0, whichever CruiseControl requires.
In Vista, go to Windows features in the control panel. there is a section there for IIS and you will find the scripting setting under the IIS 6 compatibility section
I just had this same issue when I installed CCNET 1.5 under Windows 7/IIS 7.5
You need to configure the app pool for the ccnet site. Under the Basic Settings for the application pool, set 'Managed pipeline mode' to 'Integrated'.
