Admin can map a network drive but when using the user account cannot acces

Hi

I have manually mapped a network drive on a Windows Pro SP2 network on a clinet workstation, running XP pro SP2 however I can access the drive using my admin account but when i use the users account for this workstaion i get the access denied message, the drive should be laoding up as part of a group policy but isn’t.

Will setting permission on the drive to allow the user access help?
