How do I fix a Server Application Unavailable error with ASP.NET 2.0 and Windows 2000 Advanced Server?

Posted on 2008-10-28
Last Modified: 2013-12-14
I am running 3 websites on my Windows 2000 Advanced Server with IIS 5.0, my default website was an ASP application that is no longer being used so I deleted it from IIS 5.0 and installed a ASP.NET 2.0 web application, IIS 5.0 was already installed on the server and I then installed .net 2.0 framework and moved the new site over to my server.  When I try to view the website from Internet Explorer 6.0 all I see is Server Application Unavailable.  I have gone into properties, directory and removed and created a Default Application.  I have also gone to a cmd prompt and did aspnet_regiis -i and i still get the same error.  When I look at my log files the error messages I see are:

Error(big red x) Failed to execute request becuase the App-Domain could not be created.  Error: 0x80070005 and then

Warning(yellow exclamation point) Failed to initialize the APPDomain:/LM/W3SVC/1/Root
Exception: System.IO.FileLoadExecution
message: Could not load file or assembly 'system.web, version=, culture-neutral,

I have no idea what whate else to do, any help you could provide would be greatly appreciated.

or you can reset the Code Access Security Policy to the default settings.
To do that run mscorcfg.msc (.NET Configuration Console), select Runtime Security Policy from the list on the left. In the right pane under Tasks you will see Reset All Policy Levels.
NOTE: Make sure you run mscorcfg.msc in the folder that has the highest version number if you run more then one .NET SDK version installed. This is what I did. You may want to reset the CAS Security Policies on all versions you have...

Thanks for your input, but there was nothing at the link on the article you referred to and I reset the security policy and I am still getting the same error message.

This may be a security risk, but what I did was go into the website in IIS, clicked on properties then went to operators and added ASPNET account to the list of operators for the website, nothing else I tried worked.  Thanks for the input!
