I've had this problem in the past, and the solution was always a configuration issue, or needed to run aspnet_regiis -i or something. But aspnet_regiis doesn't fix the problem, and I can't find anything that would be wrong in any configuration file.
Is there some log that I'm not looking in that would tell me exactly what "500 - Internal server error" I'm actually hitting?
If it's the 500 - Internal Server Error page that looks like this that you're seeing:
Then you can have IIS7 to pass the detailed error back to the client by configuring the following:
<system.webServer>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
If you're using IE then remember to turn off Show friendly HTTP error messages (in Tools -> Options -> Advanced), but you knew that already :).
If that still doesn't shed any light on the problem then you can use Failed Request Tracing which is a very effective diagnostic tool:
Troubleshooting Failed Requests Using Tracing in IIS 7
Administrative Tools / Computer Management / Event Viewer / Application Log
I think.. Not in front of a windows box right now. You should see in that log some events that correspond to your 500 errors. They will give you more info.

The Issue
I have cloned down an exiting web forms project and when I try to build, I get the error;
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Below this error, the "Detailed Error Information:" section provided a config file path that seems to point to the correct place, accept to the machine of the previous contributor of the solution.
Below is the approach I took to try resolving this issue
Initially, from this, I tried finding out where this incorrect file path is coming from but came across nothing even vaguely relative so I tried googling the error itself.
I came across this question:
How do I resolve "HTTP Error 500.19 - Internal Server Error" on IIS7.0
An answer provided by Bruce mentioned to:
"Check the directory and see if that user has appropriate rights to
it".
In an attempt to do this, I had a quick google and same across the following question: The requested page cannot be accessed because the related configuration data for the page is invalid error
From intermension's answer, I gathered that it was "ApplicationPoolIdentity" that was not assigned the correct permissions so in ettempting to resolve this, I visited the following link. IIS7 Permissions Overview - ApplicationPoolIdentity
I followed Jon Adams' steps successfully as shown here:
This was unsuccessful and I'm unsure of where to go now.
Thank in advance! :)
You can follow there steps:
Check which application pool your website is using
Change it to use ApplicationPoolIdentity if it is not.
Go to your website directory and search for Application Pool Identity user which has format IIS AppPool{AppPool Name} e.g. IIS AppPool\DefaultWebsite and give it read permissions
In IIS Manager select your website in the left pane and then in right pane double click the HandlerMappings icon to ensure that handlers list show up.
I've set up a new Windows 2012 R2 server running IIS 8.5.
We noticed that when an error occurs (eg the ASP.NET State Service was not running) that instead of outputting a 500 status code error screen, the request actually returns a totally blank page (only headers - with no content). We obviously need to see the errors and serving 200 OK for an error could be very problematic for indexers like Google etc or any wesite monitoring tools (which would not notify us that the site had gone offline).
On our other servers (IIS 7) we see the "yellow error screen" with a message like "could not connect to state server" (or similar).
What could possibly be wrong here? Is there some setting to globablly disable all errors (but this would be stupid if it also serves the 200 status code) or could something else be getting in the way?
The only other thing which could be interfering is we've got ISAPI_Rewrite installed on the server (but this doesn't usually cause this problem).
Thanks!
Had a similar issue on Windows 8.
In settings search for "Turn Windows features on or off".
Check that the following features are enabled
"/Internet Information Services/World Wide Web Services/Common HTTP Features/HTTP Errors".
"/Internet Information Services/World Wide Web Services/Common HTTP Features/Static Content".
You need to ensure Server Side Debugging is not enabled in the ASP module.
Classic ASP server 500 errors are returned as 200's. An attempt is made at opening the Server Side Debug Application, that then can't be found and IIS subsequently returns a 200 response and a blank page.
Make sure that you are not calling Server.ClearError() in Application_Error of Global.asax.cs that ended up being my problem.
Ripping out all Global.asax code helped me to find the cause of the error.
After that, the IIS started to return the error page as expected. Then, after the fix is applied, I returned the Global.asax code back.
Maybe this case helps you.
I had a similar issue when requesting the Default.aspx (set as page default in directory). The Server returned status 200, but the Content was blank.
In this case it worked to switch the Application pool's managed pipeline mode from integrated to classic.
Make sure you have enabled HTTP Activation
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
I have also added my IP to the firewall rule. I am a beginner in Azure.
I am getting the above error while trying to run the azure web project. I have added following tags after going through some articles but none help me.
<validation validateIntegratedModeConfiguration="false"/>
<identity impersonate="false"/>
Basically, your application is throwing an unhandled error. You will want to know what the real error is, as Error 500 is just a generic way of saying: something happened.
You can deploy your app with customerrors being OFF so you can actually see the real error (Check this link for sample instructions: http://www.serverintellect.com/support/programming/custom-errors.aspx ).
Alternatively, if you're using WebRoles, you can RDP into a server instance and check Windows EventViewer, the details of the error will likely show up there.
In my case, I was using code downloaded from durandaljs.com. The "Build Action" on my default page (index.html) was set to "None", so this file was not uploaded to Azure during publish. Fixed by changing the "Build Action" to "Content".
Troubleshooting IIS via Remote Desktop really helped me figure this out. Choosing the "Enable Remote Desktop for all roles" when you publish, then in Server Explorer, expand Cloud Services, etc., then right-click your instance and choose "Connect using Remote Desktop".
This may be a proxy related issue.
Try adding these to your *.config files:
<system.net>
<defaultProxy useDefaultCredentials="true" />
</system.net>
I'm moving a pretty basic site from Win 2003 to Win 2008 R2. The site is getting the error listed below. How can I diagnose this? I moved a number of other sites between these 2 servers & this is the only on that is receiving this error.
I've seen the other posts on this issue, but none of them list a solution that works for me.
HTTP Error 500.19 - Internal Server Error
Error Code 0x8007000d
Config Source -1: 0:
UPDATE:
Here are some notes on what I checked:
1) Permissions via Process Monitor. The config file is being opened correctly.
2) .Net version - Tried multiple settings
3) Integrated vs classic pipeline
4) change enabled 32 bit to true
5) I have not tried Aspnet_regiis.exe yet because the other sites on the new box work fine.
Next I'm going to try & comment out various items in the config file
I found the issue! The issue was the following line in web.config. I found this by commenting various things out in web.config until the site worked. But why is this line an issue on my new 2008 box with IIS 7.5? What isn't installed or configured?
Update:
This was the line I commented out. Could this have been related to IIS Feature Delegation? If config settings in the <system.webServer> element are causing this error then Feature Delegation settings could be the problem.
<httpRuntime maxRequestLength="1000000"/>
run->cmd
run "c:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i"
Run this command as a Administrator
You might have used the incorrect asp.net version. please check which version is selected from the iis application pool.
you probebly change your NT password.
Enter to IIS right click on your application -> manage application -> advanched Setting -> physical path credentials.
good luck
Please check this topic for possible answer:
How do I resolve “HTTP Error 500.19 - Internal Server Error” on IIS7.0
Answer that is not marked as resolution helped to me. I was missing: Url Rewrite Module
In my case the issue was solved by running VS2017 in admin mode.
I have created one test.aspx and my local machine it is working fine. Once I upload the same to server the page is not working. It's showing
500 - Internal server error. There is a problem with the resource you
are looking for, and it cannot be displayed.
It is impossible to help you without getting more info about the IIS configuration on your local machine and the server.
However, here's a quick stab of some things you should look at:
Check if Asp.net is installed on the server.
Make sure your app is targeting the proper .Net version that is on the server.
Check if all the assemblies your code is using are deployed correctly on the IIS server.
Add some exception handling and error logging to your code.
In particular, I'd venture to make a wild guess that your page is using some code that requires the IIS7 integrated pipeline and your server is either running IIS6 or is running IIS7 in classic mode. Though this is a stab in the dark and could turn out to be completely wrong. :-)
500 server errors are as useful as saying 'something broke'. They are the result of literally any exception you code throws plus anything else IIS croaks on. From your error msg, it sounds like an IIS config issue but it could still be your code. attaching a debugger to it would eliminate that possibility.
If you haven't looked at the server event log you can see if it registered anything.
There are a number of things that you can do to try to get a better, more specific exception. One way I try to diagnose them is to connect a remote debugger so I can see what's going on. If you have access to do so, I'd go that route.
You will need admin access to the server to install the Visual Studio remote debugging client (I'm assuming this is a .net app).
Another thing that can help are try/catch blocks and logging to a file or the event log--but have have to change your app most likely to implement that.
You have probably forgotten to upload the associated .dll. Have you tried right clicking on the project and using the publish feature?
If you are using IE, then you also need to turn off the "Show friendly error messages" option in Tools - Options - Advanced settings so that you get more details.
You may also need to change the web.config file so that error message details are shown, see the CustomErrors tag.
