The two problems I can think of (Not having NT, IIS) are permission settings in both NT and IIS. try running the EXEC() on something that stays in /root/webpages/ and see if you get the same results. I wish I had more cpu time with nt but the only time I have on it is setting up permissions for network conections. hope something clicks for ya soon have fun I am Patrick
