This little experiment might give you a pointer. Here is what I typed on my
machine:

1. runas /user:config cmd
  2. net use p: \\fnlhome\c$
  3. exit
4. net use
C:\Temp\Radio>net use
New connections will not be remembered.
Status Local Remote Network
--------------------------------------------------------------------------
Disconnected \\ipex2000\d$ Microsoft Windows Network
The command completed successfully.

As you see, drive P: does not show.

5. runas /user:config cmd
  6. net use
New connections will be remembered.
Status Local Remote Network
---------------------------------------------------------------------------- 

---
Unavailable  P:        \\fnlhome\c$              Microsoft Windows Network
Now drive P: is visible but unavailable
  7. net use P: /del
      P: was deleted successfully.
  8. exit
In other words: I spawned a command processor under the same
credentials as the original command processor. I was then able to
delete the mapped drive. However, this will NOT work if you have
any open handles on that drive.
