A Windows 2003 update messed up my server bad, so I had to reinstall .net v2. Now I can't access any .aspx pages (html load fine). When I try, I get the following error:

Server Error in '/' Application.

  • @user Someone on Google got it to work by re-installing IIS. But you should take a hint from the close votes. :)

  • Serverfault will be a better place for this. You will also want to post more details about your situation. May 10, 2011 at 17:51

Probably need some more information to try and resolve this any further, but I would suggest you need to run the ASP.NET IIS Registration Tool (Aspnet_regiis.exe) after installing asp.net

  • I had already tried aspnet_regiis -i, but it didnt help...
