On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G: if that matters. Other mappings work fine. Other profiles one the same machine have no problem seeing G: I can access the G: just fine typing it into the address bar or in CMD shell.
I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off, on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd. ref
We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable.
So, anyone have any idea why XP won't show this drive letter? Or how to fix it?
