VB Script for drive mapping

Posted on 2009-07-06
Last Modified: 2012-06-27
I am in the process of learning vb scripting but still not there yet to able to troubleshoot this VB script that suppose to delete existing drive mapping and then map fresh new drives. I am mapping drive to Windows 2003 and Windows 2008 server shares. Following are the errors\problems relates to this script. First of all I will confess that I did cut and paste couple of vb scripts from solutions presented at to find a working one for myself, so please bear with me when you go through it.

1. First, at this time I am running it on my PC as a test script by double clicking on it. It works intermittently. Sometimes it does not delete drives before mapping and sometimes I do not find all my drives.

2. I am mapping home drives using profiles in active directory. I like to know how I can map Home drive for individual using script.

3. Past weekend I ran a bigger test and use GPO to deliver mapping drives using this script. I saw my entire drives letters but there were missing server names along shares. E.g. instead of  Ch data on Server1 (Server1)' (L:) I was getting Disconnected drive (L:) even though they were working, but when I try to disconnect them I got drive path not found message.

I may be asking too many things here. Please ask me questions if you are not clear. These are the problem I need to resolve before I try again next weekend. Thanks in advance.

Best Regards

I know this doesnt really answer your question, but have you considered just making a simple batch file using the "net use" commands?

net use <driveletter>: /delete
net use <driveletter>: <path>

Just thought I would throw that out there since nobody has responded yet...

Thanks for your comments. I have been using "Net Use" commands in my batch files for past few years without any problem. Recently I added Windows 2008 domain controller to my doamin and wanted to add shares by editing my existing bat file. However, i did not work and I always get this Error 1326 'Unknow username or bad password". vb scripts seems to be a solution for this error. If you know any other way that let me map drive to windows 2008 share using my bat files then I am willing to try. Thanks

We have done away with login scripts altogether and instead have mapped drives using Group Policy Preferences. The nice thing about Group Policy Preference Drive Mappings is that they are persistent. This works well for travelling users as the drives will say Disconnected network drive, until they are back on the network via VPN. Then they can connect to the drive without launching a login script. This will also reduce the amount of time at login as it is done behind the scenes.

This has eliminated a ton of time in troubleshooting and we can base our drive mappings off of AD groups.
Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

John, I appreciate your response. I have tried to use Group Policy Preference Drive Mappings but not able to make it work. Just to let you know our enviornment so may be then you can tell if this will work for me. I have mix versions of Domain controllers, four of them are Windows 2000 and one Main domain controller is 2003 and another one is 2008, so my Domain Functional Level is Windows 2000 Native and Forest Functional level is Windows 2000. Is there any chance that ican use Group Policy Preference Drive Mappings?

          I am still trying to get my vb script working. This is my 2nd script that I am working on. It does what it suppose to do when I run by double clcking it on my PC, but when I use the same Script using GPO; it give me drive mappings without Server and share name. e.g. it gives me "Disconnected Network drive (L:)" I can click on it to open this drive. Same thing happening to other drives too. Please someone look at my script and see what i am doing wrong. Thanks

Here is an example that might help you out ;-)

Set Network = CreateObject("WScript.Network")
Set Objdomain = Getobject( "LDAP://rootDse")
Domainstr = Objdomain.get( "dnsHostName")
StrComputer = Network.computername
Set localDrives = network.EnumNetworkDrives
if LocalDrives.Count > 1 then
	For i = 0 to localDrives.Count -1 step 2
		On Error Resume Next
                'We are mapping H: using the domain profile so dont delete it here, or remove this statement'
		If Not localDrives.item(i) = "H:" then
			If Not localDrives.Item(i) = "" Then
				Network.RemoveNetworkDrive localDrives.Item(i), True, True
			End if
		end if
End If
'Create mappings based on security group memberships'
For Each GroupObj in UserObj.Groups
	On Error Resume Next
	Select Case GroupObj.Name
                'Echo the security group remove if you understand
                WScript.Echo GroupObj.Name
		case "DL SG LOC Finance"
			Network.MapNetworkDrive "G:", "\\UNC"
                        'If double mappings are made you might delete them here'
			Network.RemoveNetworkDrive "I:", True, True
			Network.MapNetworkDrive "I:", "\\UNC"
		case "DL SG LOC Corperate_ICT"
			Network.MapNetworkDrive "K:", "\\UNC"
	end select

I have opened this question few months back and I decided to use bat files again even though I was looking for some help in my posted vb script.
