Tried it and it still doesn't work. Are they any settings that you know of that can fix this in W2003?
Look at the permission set for wscript.exe.
Make sure execute privs are set for you.
If all else fails, use this tool:

Run the tool, execute your script then find "access denied" or "denied" anywhere in the results.
