I have a small network (5 PC’s) with a Windows 2000 machine acting as a server with a single shared folder. The owner bought a new PC with Windows 7 Professional. All was well until I tried to map a drive to the Windows 2K share. I can see it but I can’t log in. Spent about 2 hrs with Microsoft tech support (three different levels) and another hour with Dell. They couldn’t do it either. Since I have no faith in either I was wondering if anyone else knows why this can’t be done. Have tried this with both 32 and 64 bit systems.
