If you dont have sms / sccm client in your gold disk then GPO is the next best thing to get the SCCM client out into your environment.
This is a real nice and clean install script for IE 7 which i have modified to install SCCM. http://www.symantec.com/connect/blogs/installing-application-using-vbscript
object.Run(strCommand, [intWindowStyle],[bWaitOnReturn])
'INSTALL MS INTERNET EXPLORER 7 USING VBScript
Set objShell = WScript.CreateObject("WScript.Shell")
spath = objShell.CurrentDirectory
If fso.FileExists(spath & "\IE7-WindowsXP-x86-enu.exe") Then
path = """" & spath & "\IE7-WindowsXP-x86-enu.exe" & """ /passive /norestart /update-no"
objShell.Run(path, 1 ,True)
i = 0
'INSTALL MICROSOFT INTERNET EXPLORER 7
i = objShell.Run(path, 1 ,True)
If (i = 0) Or (i = 3010) Then
'WRITE EXIT CODE [0-success/3010-success&requires reboot] TO EVENTLOG
objShell.LogEvent vbLogSuccess, sLogHeader & "Microsoft Internet Explorer 7 installation completed successfully." & VbCrLf & "Exit code: " & i
