C:\>cd WINDOWS

C:\WINDOWS>cd Microsoft.NET

C:\WINDOWS\Microsoft.NET>cd Framework

C:\WINDOWS\Microsoft.NET\Framework>cd v2.0.50727

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>
C:\WINDOWS\Microsoft.Net\Framework\v2.0.50727>aspnet_regiis -i

it will run for 2 minute then restart iis (using command "iisreset" in command prompt)
Now u will be able to run aspx pages.
