Here's the UDF - I created it today (I know, not the tidiest - still got to clean it up a bit)

Code:
Function MapDrive($Drive, $Share, Optional $Server)
	If $Drive NOT "" AND $Share NOT ""
		Use $Drive /DELETE
		If $Server NOT ""
			Use $Drive "\\" + $Server + "\" + $Share
		Else
			; Used for \\server\share (i.e. the users home folder from AD)
			Use $Drive $Share
		EndIf

		If @ERROR = 0 OR @ERROR = 1202
			Color w/n
			? $Drive + " drive - " + $Share + " on " + $FileServer + " - Attached"
		Else
			Color r+/n
			? "Cannot connect to " + $Drive + "!! " + @SERROR
		EndIf
	EndIf

	Color w/n
EndFunction
