Search the board for elaborate solutions which use INI files for mapping, but depending on how your groups are structured one of these should fit:

Code:
Use K: /DELETE

Use H: /DELETE

  

Select

Case InGroup("\\RDC\GroupName")

	Use K: "\\Server\Folder"

Case InGroup("\\RDC\GroupName2")

	Use H: "\\Server\Folder2"

Case InGroup("\\RDC\GroupName3")

	Use K: "\\Server\Folder"

	Use H: "\\Server\Folder2"

Case "True"

	; No drive mapping for this group.

EndSelect


OR

Code:
Use K: /DELETE

Use H: /DELETE

  

If InGroup("\\RDC\GroupName")

	Use K: "\\Server\Folder"

EndIf

If InGroup("\\RDC\GroupName2")

	Use H: "\\Server\Folder2"

EndIf

If InGroup("\\RDC\GroupName3")

	Use K: "\\Server\Folder"

	Use H: "\\Server\Folder2"

EndIf
