Troubleshooting Code 800704B2 - An attempt was made to
remember a device that had previously been remembered
Introduction to Code error 800704B2
This
error code, 800704B2 occurs when you try to map a network drive with a VBScript. A wild guess, you are
probably using a WSH (Windows Script Host) method called MapNetworkDrive.
The Symptoms you get with error 800704B2
A Windows Script Host message box appears and the script does not map the drive as you would have hoped.
The probable scenario is that you are trying to create a Windows logon
script.
The Solutions for Code 800704B2
My first suggestion is make sure you have the latest service pack. For once, this error really does seem to be a bug which Microsoft fix with a service pack.
See TechNet article Q328981. My reflex is to disregard people who tell
me to reboot the server, or get the latest service pack, but on this occasion
it seems a service pack will fix it.
My second suggestion would be to put a RemoveNetworkDrive statement
immediately before my MapNetworkDrive method. J.B. Reminded me that RemoveNetworkDrive takes two true parameters, so try: RemoveNetworkDrive x, true, true. See
more on remove network drive here.
My second suggestion was actually sent in by RS - see here
Set WshNetwork = WScript.CreateObject("WScript.Network")
Letter = "X:"
' this triggers the bug if the drive "Letter" is not
available (with a red "X" in My Computer):
WshNetwork.RemoveNetworkDrive Letter, True, True
' the workaround
Dim AllDrives, i, WshShell, Command
Set AllDrives = WshNetwork.EnumNetworkDrive()
For i = 0 To
AllDrives.Count
If AllDrives.Item(i) = Left(Letter, 1) Then
Set WshShell = WScript.CreateObject("WScript.Shell")
Command = "net use " & Letter & " /delete /yes"
WshShell.Run(Command), 7, True '
minimised, wait until completion
Set WshShell = nothing
End If
