Ok I changed it but still the same result. The T: loads just fine but the printer, P: and S: still do not load unless I run the script from my machine

$REGkey = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"
WRITEVALUE($REGkey,"HideFileExt","00000000","REG_DWORD")


If InGroup("urfcu-tech")
USE T: "\\fileserv\dept\tech$" /Persistant
If AddPrinterConnection ("\\unity\brotherh") = 0
? "Added printer connection...."
If SetDefaultPrinter ("\\unity\brotherh") = 0
? "Set default printer to \\unity\brotherh"
Endif

IF INGROUP("urfcu-cs")
USE S: "\\fileserv\cardsource" /Persistant
EndIf

IF INGROUP("Domain Users")
USE P: "\\fileserv\apps\apps" /Persistant
EndIf
