VB Scripts

Good Day,

I just built a new 2003 file server and have migrated about 40 users to this server.  To map all the shares I did the most basic vbscript possible that looks like this,

Set objNetwork = WScript.CreateObject("WScript.Network")
objNetwork.MapNetworkDrive "m:" , "\\ptcfiles\personal user files"

Set objNetwork = WScript.CreateObject("WScript.Network")
objNetwork.MapNetworkDrive "t:" , "\\ptcfiles\battery tech"

Set objNetwork = WScript.CreateObject("WScript.Network")
objNetwork.MapNetworkDrive "j:" , "\\ptcfiles\tech sale"

And so on.

There are a total of 6 shares that are mapped for all the users.  But now the problem is that I don't want all these shares to get mapped for every single user, how could I change this script around so that only specific users get the T:\\ share for instance mapped to their machines while others don't.  I wasn't going to worry about this much but today I noticed for one user a certain program must me mapped through a share letter T:\\ in order for it to work, don't know why but it does, and since I allready am using T:\\ letter as a share i'm having a problem, so for that user I need to set the script so that the T:\\ is not mapped.
