I created a web application by going to IIS right-clicking on Default Web Site and selecting Add Application. Then I give the Alias name, select DefaultAppPool and point it to Physical path.
When I try to browse to http://localhost/mywebapp I get 'Access is denied' with following details:
Error message 401.2.: Unauthorized: Logon failed due to server
configuration. Verify that you have permission to view this directory
or page based on the credentials you supplied and the authentication
methods enabled on the Web server. Contact the Web server's
administrator for additional assistance.
Anonymous Authentication is enabled on the IIS Website.
The web application is ASP.NET MVC5 application.
The web application is running under its default identity: ApplicationPoolIdentity
Here are the settings for DefaultAppPool
Make sure your application is not on a network share or in the windows user (magic) directory. (It can be in the Visual Studio default magic user directory if you follow my instructions below)
If you're on Win7, create a new MVC 3 application, ^F5 to run. Then in solution explorer, right click the project and select properties. In the left pane, select the Web tab. The default is Cassini ( Use Visual Studio Development Server). Select the next radio, Use Local IIS Web server. Now ^F5 and it will launch your app from IIS. You can also find your application in IIS manager and in the right pane, select browse 80. Now that it's working, compare the differences in your two application.
Your approach should also work. You might try creating a new MVC application and use your approach to test on IIS. The most common mistake is creating a vDir, not an application
The error message is pretty good. To set ACLS on the application pool identity, follow the instructions under Securing Resources at http://learn.iis.net/page.aspx/624/application-pool-identities/
Also see Understanding Built-In User and Group Accounts in IIS 7
IF the new MVC app should fail, repeat, but create a Web Forms app.
Make sure IUSR has permission to the directory that webapp is sitting in.
Also, if your application is accessing permissioned resources(File IO, MSMQ...etc), you will have to change the Identity of the app pool or make sure ISUR has permission.
Make sure that the NETWORK SERVICE account (or whatever system account IIS is using) has permissions to the application folder.
To check the system account that's being used, go to the application pool settings, and the system account will be listed under the Identity tab:
EDIT
Make sure that the application is using the correct application pool. Also, if you haven't already specified a default document, that could be your problem. You can test this by including a page name in the URL, e.g. http://localhost/mywebapp/default.aspx

I get the following .NET error when trying to load my Orchard CMS website:
Access to the path '\\.........\www\App_Data\Dependencies\Lucene.dll' is denied.
Exception Details: System.UnauthorizedAccessException: Access to the path '\\WDP\DFS\30\7\4\5\3024678547\user\sites\5481517.site\www\App_Data\Dependencies\Lucene.dll' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
How do I actually go about granting access rights? I've googled and found I should go into the server and right-click on the directory and edit the properties. BUT, I am in a shared hosting plan and don't think I can do that.
Am I pretty much at a dead end?
Things I've tried:
Setting file permissions through FTP, but I get a:
500 'SITE CHMOD 777...command not understood
I've downloaded and installed IIS Manager and successfully connected to my site, but still did not find any options to set permissions in there.
I've also called Network Solutions, but all I was told was to try to do the file permissions settings (as I mentioned above).
Thanks in advance.
I am running IIS 7 on Windows Server 2008 R2 with PHP 5.4. One of my PHP scripts is trying to access a file on a protected network share using a UNC path. How can I change the IIS service account to an account that has permission to access the share? This is really easy to do on Apache HTTP server (you just change it), but it's not clear how to do with IIS. What can I do?
Update:
I was able to get things working using the "Connect As" option in the "Basic Settings" of my website and then specifying an account that has access to the network share. It appears that my problem is related to this question:
https://serverfault.com/questions/366234/iis-identities-application-pool-vs-connect-as-in-basic-settings
For IIS 7 running on Windows Server 2008 R2 ... In the IIS Manager, select the Application Pool under which your Web Site is running.
Click "Advanced Settings". There will be an entry for Identity (it is under the Process Model section). Click it, provide credentials for your account that has permission to access the share.
UPDATE
You should make sure that if you are using an Active Directory Domain Account, you provided that correctly under Identity for the running App Pool. For example, MYDOMAIN\myAccount.
After making this change, you will need to do the following:
Stop the Web Site.
Recycle your Application Pool.
Start the Web Site.
UPDATE II
From the comment discussion on this answer, #HydroPowerDeveloper was able to get the PHP script to be able to access the network share via UNC path using WebSite -> Basic Settings -> "Connect As" and setting the credentials there.
In the past, I have always used the approach of setting Identity via Application Pool and that has allowed my code to access Network shares via UNC path.
However, all of the sites/applications I have deployed on IIS are .NET based WCF or ASPX sites.
I would speculate (but am not 100% certain on this, would need research/testing to confirm) that the Identity specified in the Application Pool is used by executing .NET code, whereas the "Connect As" is used by the PHP script.
Generally the Application Pool is set using the least amount of privileges as possible.

The easiest route is to allow access to the current IIS account.
In Explorer, navigate to the shared directory.
Right Click -> Properties -> Security
If you don't see the expected IIS user in the list (Group or user names), edit and add the user as required.
I used "NETWORK SERVICE" -> Check names.
The detailed instructions are on that site.
In this way, the system is still restricted, we're ONLY allowing access to specific directories, we don't need to create any new users, we don't need to recycle the application pool and we don't need to perform any nifty impersonation code.
To resurrect an old question...
I've just been setting up a Win 2016 server that uses some Perl to access a UNC share. I set the Application Pool to an account that I verified had the correct permissions on that share. I then set up my site to 'Connect as...' (under 'Basic Settings') the same user. I still couldn't get access working.
Much head scratching later, I realised that my 'Virtual Directory', cgi-bin, was running under the original 'pass through' account. I then set up the virtual directory to 'Connect as...' the same account as the site and the application pool and, bingo, it all works fine.
So, remember to update any Virtual Directories as well as the site and App Pool...
I have a web application developed in ASP.net 4.0 and hosted in IIS7(ProdServer).
In one of the pages I am creating a file and storing it in \someOtherServer\Storage\
folder.
when I log on to production server and hit run and \someOtherServer\Storage\
I am able to browse the folder.
When I run my ASP.net application I get the error
Access to the path '0' is denied.
Exception Details: System.UnauthorizedAccessException: Access to the path '0' is denied.

You will have to look at the identity of the apppool under which your ASP.net site is running and make sure that account has permissions to the resource on the other server.
To do this in IIS 7, do the following:
Open IIS manager and browse to the site where this is happening.
Right click on the site and select Manage Application -> Advanced settings.
The top most setting will show the name of the application pool you are running under. Most probably it is DefaultAppPool, but it could be something else too (preferably it should be something else).
Now cancel and click on the Application Pools node in IIS manager and right click on the application pool you saw above and select advanced settings.
Look at the Identity setting under process model - this might be ApplicationPoolIdentity. For you to access a resource on another machine you will have to run it either as NetworkService or as a domain account. I suggest you try the one and then the other. The domain account should be a service account which password does not expire (otherwise every time it expires you will have to retype it in here). Make sure that the domain account has access to the shared resource on the remote server.
Hope that helps someone.
Setup
There is an IIS 6 application running in a .NET 2.0 App Pool on Server-A. IIS 7 Server-B needs to host that same code-base under a different URL. I created a virtual directory under Server-B's website to the network path of the application on Server-A. I've enabled this virtual directory on Server-B as an application running in its own .NET 2.0 App Pool in Classic Mode. Both app pools run as the same domain account that has access to that folder.
Issue
When accessing the site from Server-A it works fine. Accessing it from Server-B however generates the infamous "Required permissions cannot be acquired." error.
I have been trying to find a solution to this problem for two days. The two most common solutions have been to check the CLR Trust level on the Server-B box or to set the Load User Profile property on the App Pool to "True". Since I have full administrative rights I set the Trust level to Full and set the profile sitting to "True". Strongly naming all the assemblies the application and throwing them in the GAC is not where I want to go.
I'm sure I'm just missing some configuration somewhere. Any ideas? Thanks.
We have had a similar problem once.
In our case the user that was the identity of the app pool have never logged on to the server. Therefore, there was no local user profile, therefore there was a problem when the system tried to use the profile.
As a test try and set the identity of the app pool to the admin account you use to log in with.
Manually verify that user can access that share. Try logging into windows as that user and then accessing that share (or fake it with something like a "runas /User:{Domain\UserName} net use {\server\share}").
Also try loading ShareMonitor wherever the files actually live. It should tell you what user account is trying to access a given share. It might not be the account you think it is. I cannot recall if it was this program or not, but I have used something very similar in the past to figure out a really odd permission problem.
That should determine if it is a file access problem. If it isn't, then all I can say is to make sure you have ASP.NET enabled (on windows server it is a separate option).
Also check out the file permissions on your "Temporary ASP.NET Files" directory. I've had to explicitly add users write access to that before to get things working.
in my case my IIS App Pool had LoadUserProfile=false, so it was not loading the profile of the app pool's Identify (a domain account). This caused this unable to acquire permissions even though my Webroot files/folders (including /bin) had correct permissions. Setting LoadUserProfile=true fixed the issue for my setup.
I would set that application pools identity attribute (in advanced settings) as administrator. That way, you application will work on the server, just like it works on the local setup.
I am getting this errror in my newly created website in Windows 7 and IIS 7.5. I created an SSL certificate and done binding new website.
HTTP Error 401.3 - Unauthorized
You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server.
Earlier when I created the website, I selected 'application user(pass through authentication)' in 'Add Website' dialogue. and when I click "Test Settings ..." button, I get this error message:
The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path. Then test these settings again.
Please suggest solution to this.
Thanks.
I had the same issue, ensured my DefaultAppPool was running under ApplicationPoolIdentity and the DefaultAppPool had permissions to the folder, but some files still didn't load.
Turns out my problem was that the anonymous authentication user was set to someone else instead of ApplicationPoolIdentity
Screenshot
Make sure that application pool of your website and website both are running under the same identity. Then make sure that this identity has required permissions on the virtual directory. I had exact same issue and above two checks fixed it.
IIS 7 also creates "IUSR" as default user to access files via IIS. So make sure user IUSR has read access to files/folders.
How to check if IUSR has read Access? Right Click -> Folder -> Properties -> Security Tab See if IUSR is in Group or user names list, If No.
Click Edit -> Add -> Advanced -> Find Now -> Select IUSR and click OK -->click Apply
The below worked for me. I did not set up an SSL, just a new website within IIS. Upon doing so I was immediately unable to access the website with this error message.
When I created the new website, a new Application Pool was also created. The Identity of this Application Pool was set to ApplicationPoolIdentity. As mentioned by Suhas, the Application Pool of the website and the website itself must be running under the same identity. (I do not know how to check the identity of the website, but the Application Pool's Identity can be checked by going to Application Pools and looking at the Identity column). The default Application Pool name is DefaultAppPool.
I added permissions to the site (right click the site name -> Edit Permissions -> Security -> Edit -> Add), linking the site to the DefaultAppPool object, which in turn gives the site access to the default user and it's settings. (The default user is created when IIS is installed. Read more about this in Microsoft's docs).
I thought this would be all that's needed to obtain access, but this is incorrect. The website's Application Pool must also be set to DefaultAppPool. This can be done by right clicking on the site -> Manage Website -> Advanced Settings -> Change the Application Pool value to DefaultAppPool.
