Just an idea for you..
'Set registry key
'vbscript
Dim oShell
Set oShell = CreateObject("Wscript.shell")
oShell.RegWrite "HKLM\Software\Microsoft\Windows\CurrentVersion\Runonce\command","reg.exe import \\altiris\express\regfiles\zack.reg","REG_SZ"
Use run once, change command to whatever you want, force user logoff. Next time they login it should run.
