It is common practice to use Columbus scripts to do administrative tasks, like create local groups and users, but Columbus has no built-in command to do this.
A very efficient way to accomplish complex tasks in packages is to use embedded VB-Script in a standard Columbus script.
The following script is an example of how to create a local group and add users and an existing global group to it.
BEGIN SCRIPT 'VBScript' 'Main' '%_machine%'
Function Main(strComputer)
ON ERROR RESUME NEXT
Const LOCAL_GROUP ="a_new_local_group"
Const GLOBAL_GROUP = "an_existing_global_group"
Const DOMAIN_NAME = "your_Domain"
Const USER1 = "an_existing_user"
Const USER2 = "an_existing_user"
'Create the Local Group
Set objComputer = GetObject("WinNT://" & strComputer & ",computer")
Set objGroupAdd = objComputer.Create("group", LOCAL_GROUP)
objGroupAdd.SetInfo
' Add Users to the Local Group
objGroupAdd.Add "WinNT://"& DOMAIN_NAME & "/" & USER1
objGroupAdd.Add "WinNT://"& DOMAIN_NAME & "/" & USER2
' Add a Global Group to the Local Group
objgroupAdd.add "WinNT://"& DOMAIN_NAME & "/" & GLOBAL_GROUP
End Function
END SCRIPT
