Mapped Drives and vbscripts

Hello

If a vbscript is used to map network drives for users, but that script does not always run properly, will adding the mapped drives manually affect the script or causes any issues?

Regards,

Yes, if you try to map to a drive letter that already exists, you'll get an error. However, you can catch it in your script before it happens.

For example, I use this script:

Code:

 '  Based on a VBScript by Guy Thomas February 2004.
'  http://computerperformance.co.uk

' This line creates the Shell or environment for the commands - do not alter
Set WshShell = WScript.CreateObject( "WScript.Shell ")

' The section sets the variables. Note the pattern variable = value
' You may change the variable names if you wish to check your understanding.

Set objNet = WScript.CreateObject( "WScript.Network ")
Set CheckDrive = objNet.EnumNetworkDrives()

' Be very carefull with the DriveLetter, the value must be a CAPITAL letter
' map drives

MapThisDrive  "P: ",  "\\server\share1 "
MapThisDrive  "Q: ",  "\\server\share2 "


Sub MapThisDrive(DriveLetter,RemotePath)
	' This sub routine does the work.

	AlreadyConnected = False
	For i = 0 To CheckDrive.Count - 1 Step 2
		If CheckDrive.Item(i) = DriveLetter Then AlreadyConnected = True
	Next
	
	' This tests to see if the Drive is already mapped, and if yes then disconnects it before reconnecting it
	If AlreadyConnected = True then
		objNet.RemoveNetworkDrive DriveLetter
		objNet.MapNetworkDrive DriveLetter, RemotePath
		
	Else
		objNet.MapNetworkDrive DriveLetter, RemotePath
	
	End if
	
End sub
'  Script ends here  

The subroutine is passed a drive letter and the share to be assign to it. It first checks to see if the drive letter mapping exists and if it does it removed it before creating a new one.
