Drive letters

[MaryTibbs]

An NT station has recently altered its O drive. We use O as part of our network drive mapping but suddenly this station appears to have its O drive pointing at the local C drive. All the properties for O and C are the same but you cannot access any of the files on O. If I go to disk administrator there is no sign of a drive O and if I go to Map Network drive or Disconnect Network drive O is not visible there either. If any one can help I would be VERY grateful

hhmmmmm thats a strange one. How is the drive mapped? I.E is it going to the C$ share? I don't know why it would not appear in the Disconnect network drive, if you right click on the drive do you get a disconnect option?
What happens if you try and map another drive to O with out disconnecting?

Just had an idea, has someone created a virtual drive?

goto a cmd prompt and enter

subst O: /d

and see if this removes the drive.

OK - so when I do the subst O: /d everything reverts to as I want it. The O drive becomes the Users home directory. But as soon as log off it reverts to this strange drive that only appears in My computer - not in Drive mappping or Disk manager. So what does this subst command do and how do I make it stay that way? Your help is much appreciated and I hope you don't think I am being too thick.

The O: drive is a virtual drive.
i.e if I ran "subst O: C:\data" it would create a virtual drive which has c:\data at its root.

Check that there is nothing in the start up or any programs that require a virtual drive.

 

[MaryTibbs]

There appears to be nothing in Startup and I cannot see that any new programs have been installed. I think I am going to have to rebuild this station to get rid of it!

 

[ensorg]

Silly question but you are logged in as Administrator when you run this?

 

[MaryTibbs]

Not so silly - But yes I am

That is very strange, I have never seen it before. If it deletes it OK and lets you recreate another shared drive in its place makes me think that the command is running again at start up to restore the drive, but I have never see this before.
