How do you remap a share to a different drive?

I want to write a start up script to take an mapped drive, change the drive letter, then put a different share on the original drive. How can this be done?

From serverfault Bob

• Check out the NET USE command.

  You will need to delete the current mapping, then remap with the desired drive letters and shares.

  From NYSystemsAnalyst

• net use X: /DELETE
  net use X: \\newshare
  

  Where X: is the drive letter you want to map and \\newshare is the location of the new share you want mapped

  From Ciaran

• Absolutely.

  If for example the existing drive is X: and has \server1\shareA on it and you wanted to remap X: to Y:you could do it with a batch script.

  net use x: /delete
  net use y: \\server1\shareA
  

  If you need to pass credentials you'd have to add the username (and possibly the password if you want it to run totally automated. Note that it's a bad idea to do this with privileged accounts and there are way smarter ways. But for a quick change over this will do it

  net use x: /delete
  net use y: \\server1\shareA <password> /user:<username>
  

  If you don't include the password it will prompt. You can save this in a .bat file and it will run just fine.

  EDITED TO ADD more complete solution

  So you want to take a drive mapping X: change it to Y: and then connect X: to the new share \server1\newshare? Here you go. You can of course still pass credentials if necessary.

  for /F "skip=1 tokens=3" %%i IN ('net use x:') = DO (
          set OLDSHARE=%%i
          goto :DONE
          )
  :DONE
  
  net use x: /delete
  net use y: %oldshare%
  net use x: \\server1\newshare
  

  The for loop parses out the existing share path for the drive letter you want to change. Then you disconnect it from x: reconnect it to y: and then connect the new thing to x: all in quick succession.

  Bob : Is it possible to pick up the location of the existing share before deleting it?

  Laura Thomas : You mean determine it from the script? Possibly with a bit of fancy parsing. net use with no arguments returns all the mapped network shares. Net use with only the drive letter returns information including the remote name.

  Laura Thomas : I edited my answer above. Hopefully this is what you want. It's sort of quick and dirty but it works.

  Bob : Awesome, thanks a lot!

  musicfreak : Hmm, I'm trying to figure out what question you answered with "Absolutely". ;)
