"Server Application Unavailable" after moving to a VM

Question

User-1207316831 posted

We moved our development server to a new Windows 2003 Virtual Machine. What could be causing "Server Application Unavailable"? Our dot Net apps worked fine in our old development server. Event log shows the following:

======

Failed to initialize the AppDomain:/LM/W3SVC/2082169611/Root

Exception: System.Configuration.ConfigurationErrorsException

Message: Exception of type 'System.Configuration.ConfigurationErrorsException' was thrown.

Hi,

Please try re register ASP with IIS. You can use the following command.

1. Stop Web Services

net stop w3svc

2. Uninstall all instances of ASP.NET

aspnet_regiis.exe -ua

3. Re-install ASP.NET to IIS

aspnet_regiis.exe -i

4. Start the Server

net start w3svc

Best Regards,

Jean
