Domain Login script won’t run

We’re moving from netware to Windows 2000 active directory. We’re trying to get our active directory users to run a login script to map all of their drives etc. However, our scripts don’t work. We have the scripts in the \netlogon share on the Windows 2000 PDC. In the active directory user property, we have them set to use ‘testlogin.bat’. When the user logs in, the drives don’t map. When we run the script after being logged in, they map. (Our script pretty much is ‘net use f: \\\). We used pretty much the same setup with a Windows NT domain and had no problems at all. We’re using mixed clients, all from Win 9x all the way up to XP.
