Detailed logon script for Active Directory

Need a detailed logon script written for Active Directory.? The script will primarily map network default drives for all then will map extra drives based on group assignment.? This script will be added to other scripts; other scripts are in ScriptLogic.? The script needs to be? written so that If, Then Else statements will work and multiple alternatives can be sorted through.? for example, if a user is a member of multiple groups, the script should be smart enaough to quickly go through the assignements. I prefer the scripting to be done in VBScript (maybe WSH?) I like Powershell to but I am not sure that it can handle all of the manipulations. This is for experienced network script writers.
