Users cannot access the Z: Drive (vines files)

[BanyanAdmin]

We have windows 2000 professional and Banyan client. The problem is that standard users cannot access the Z: Drive when they log in eventhough the icon exists under My Computer. They get "Network path was not found". If I move them to the Administrators group, EVRYTHING IS FINE. I can't seem to find the permissions I need to set to solve the problem. Please Help

Run MMC, add in Group Policy, go to machine security settings, Local Policies, Security Options and change Strengthen Default Permissions of Global System Objects from Enabled to Disabled.
