My apologies for my last attempt to help. I didn't have a win32 machine to really test, I just saw the escaped character issue.

Anyway, according to Dave, you shouldn't use the UserSetAttributes function. I would recommend the SetPassword function instead for your purposes. Make sure you have adminsistrative rights on the remote machine that you are trying to modify, too. Wouldn't hurt to grab the latest version of AdminMisc from Dave as well.

Good Luck!
