Windows 2000 Prompt Authentication

[marretas 0]

Hey guys i need some help here. Well i've installed windows 2k for use as archive server. Well i've created the user account and set the premissions, so far its all ok. But now i try to connect to shared folder in the archeive server and he ask's me a 1st prompt ( only if is the 1st time i log in ) and i logon using a any account witch i ve made before. Well everything is ok, but next time i access to server archive folder he doesn't ask for authentication, so i only can enter in folder1 using Cpu1. If i desire to enter into my folder using another computer i cant because, this CPU2 already entered his user & password account. There is anyway to force users insert username & password everytime he access to archive server shared folder ?
