When trying out a tool on my Windows Server 2008R2 I had to install .NET 1.1. Unfortunately this messed up my IIS install completely.
I managed to recover most websites by running the
aspnet_regiis.exe tool again (tried both .NET 2 and .NET 4, 64-bit versions) and making sure the Application Pool is set to use the 64-bit framework version and the .NET 2 profile were applicable.
Unfortunately this didn't work for the Sharepoint services I have installed as part of my Team Foundation Server install. I end up getting the following error message:
Server Application Unavailable The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request. Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
I have been searching for hours but I did not find a correct solution yet. When I look into the event log there's no error or warning.
When I try to repair the services installation I end up getting an error saying it cannot find the services language pack and cannot complete my request.
Any ideas to solve this issue or where I can get more information without a complete reinstall is greatly appreciated.
