VBScript Login Script

Hey Everyone,

I have a domain that I have recently wrote VBScript login scripts to replace batch ones. The problem is people started getting this "local device name is in use" error message. If I go in and manually remove the network drives before I log off and log on, the message goes away. However the default for MapNetworkDrive is supposed to be non-persistent connections? The server OS is Server 2003. Here is a basic format of the script.

Option Explicit
Dim WshNetwork, oDrives, strUName, i

Set WshNetwork = WScript.CreateObject("WScript.Network")
Set oDrives = WshNetwork.EnumNetworkDrives

strUName = WshNetwork.UserName

DriveMapper "H:", "\\FileSrvG4\" & strUName & "$"
DriveMapper "F:", "\\FileSrvG4\Data",
DriveMapper "M:", "\\FileSrvG4\Images"
DriveMapper "P:", "\\FileSrvG4\Pricing"
DriveMapper "S:", "\\FileSrvG4\Sales"

Sub DriveMapper(Drive, Share)
For i = 0 to oDrives.Count -1 Step 2
if LCase(Drive) = LCase(oDrives.Item(i)) then
if not LCase(Share) = LCase(oDrives.Item(i+1)) then
WshNetwork.RemoveNetworkDrive Drive, true, true
Else
Exit Sub
End if
End if
Next
WshNetwork.MapNetworkDrive Drive, Share
End Sub

Thank you!

Yeah, is that a common issue?

But thank you Chris, A+, very helpful, and thanks for the quick reply!

We suffer from it here too, it's not all that predictable unfortunately which has always been a little odd. I suspect it's leaving something lingering in the profile which is causing it to remain persistent.

Our drive mapping routine is not too dissimilar from yours, the only difference these days is that it removes the existing mapping (even if it's the same one) and forces an update to the profile with the new mapping.

Could you show how I'd write a Sub that does a forced removal and remaps, because we started getting the error again today?

Sure, this is ours minus the logging bits:

Sub MapDrive(strDrive, strShare)
      Dim objFileSystem, objDrive, objNetwork

      Set objFileSystem = CreateObject("Scripting.FileSystemObject")
      If objFileSystem.DriveExists(strDrive) Then
            Set objDrive = objFileSystem.GetDrive(strDrive)
            If objDrive.DriveType <> 3 Then
                  ' Fixed Drive
                  Exit Sub
            End If
      End If
      Set objFileSystem = Nothing
      Set objNetwork = CreateObject("WScript.Network")
      On Error Resume Next
      objNetwork.RemoveNetworkDrive strDrive, False, True
      objNetwork.MapNetworkDrive strDrive, strShare, True
      On Error Goto 0
      Set objNetwork = Nothing
End Sub

thanks, ill see if that is more effective.
