Open a CMD Prompt as administrator (right click cmd.exe and select Run As Administrator)
1) cd\C:\Windows\Microsoft.NET\Framework64\v4.0.30319
2) aspnet_regiis -r
3) Go to IIS ADMIN
4) Select Default Web Site
5) Doble Click ISAPI Filters
6) Doble Click v.4.0.30319 and remove the extra backslash between v4.0.30319 and aspnet_filter.dll (just check if aspnet_regiis won't work)
The root cause of the problem was the setup of older .NET Framework on Windows 2008 R2
bye

Google search on my issue got me here. Thanks so much. This cures a problem, that I believe was caused by installing SEP. I need IIS for a significant app on this server. Thanks so much for your correct ANSWER
ResponderEliminarThe issue is caused by .NET Framework 1.1 installation on Windows 2008 R2.
