I have installed Exchange 2010 with SP3 on a Server 2012. The Installation was good but when i try to use the ECP via OWA a error message appears.
HTTP Error 500.21 Internal Server Error
C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\ecp\default.aspx
I already had that error on a Server 2008 r2 with Exchange 2010. there i could fix it with the command:
But in Server 2012 there is no such file.
How can i reinstall ASP.NET on a Server when Exchange is already installed?
