I recently added an Iomega ZIP 100 to a networked NT 3.51 SP4 machine. During the installation, the ZIP took over drive D: and apparently pushed all the other connections back a drive letter. The next time I booted, I received many errors, the majority were fixed by changing the path for icons in program manager to the new path. But, I have two errors that won't go away. One gives me the message: ntvdm.exe - No Disk There is no disk in the drive. Please insert a disk into drive E:. The other says: Program Manager - domain\user: progman.exe with the same message about the E:. Drive E: was previously a networked path on the server. The user can push ignore when prompted and all operates as normal. Also, it appears that the ZIP created a new hidden file called progman.gid which I have no idea what it is for, as none of my other computers contain it. How can I make these errors go away?
