Caspol no longer working

Several years ago I built a simple batch script to use caspol to give .NETFramework Fullcontrol to trust two webservers

Here is the batch file...

CD "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727"
caspol -q -addgroup 1 -site servername FullTrust
Pause
caspol -q -addgroup 1 -site servername FullTrust
pause

Now that our workstations are windows 7 this no longer appears to be working.  Any thoughts?
