I made a small kix script to deploy Symantec Antivirus v10 GRC.DAT based on Client Groups to individual Clients.
The deployment works ok, the file is copied, but the changes are not done, even after a reboot.

All Clients are put into Client Groups dependant of Nameing conventions ie a laptop is named DRKBGMOBxxx, a desktop DRKBGWSxxx etc.

Code
$NavParent = "xxxxx"
$DataLocation = ReadValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders", "Common AppData")
MessageBox("Workstation:"+@WKSTA+" DataLocation:"+$DataLocation,"Symantec Antivirus",,10)
Select
Case (InStr(@WKSTA,"DRKBGTEST04"))
$ClientGroup="SWDistribution"
Case (InStr(@WKSTA,"DRKBGSCA")) OR (InStr(@WKSTA,"DRKBGFEL")) OR (InStr(@WKSTA,"DRKBGKUR"))
$ClientGroup="SpecialEquip"
Case (InStr(@WKSTA,"DRKBGMOB")) OR (InStr(@WKSTA,"MOB"))
$ClientGroup="Laptops"
Case (InStr(@WKSTA,"DRKBGWS"))
$ClientGroup="Desktops"
Case (InStr(@WKSTA,"DRKBGW")) OR (InStr(@WKSTA,"DRDRMW"))
$ClientGroup="Servers"
EndSelect

MessageBox ("Copying file:"+ $DataLocation+"\Symantec\Symantec AntiVirus\7.5\","Symantec Antivirus",,10)
Copy "\\$NavParent\vphome\groups\$ClientGroup\grc.dat" "$DataLocation\Symantec\Symantec AntiVirus Corporate Edition\7.5\"
