SSRS: does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

In case anyone gets this error:

Server Error in '/' Application.
The current identity ({whatever domain\username}) does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.

This blog entry helped me out.  The result was odd but it worked.

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -ga "{whatever domain\username}"
 

Start granting {whatever domain\username} access to the IIS metabase and other
 directories used by ASP.NET.
An error has occurred: 0x800703f0 An attempt was made to reference a token that
does not exist.
