Thanks Jeff & Cycletech....
I was able to make my unmanaged client appear in SEPM fine.
I have mutlple groups in SEPM, as i have imported my computer AD structure. If i wanted to use GPO for SEP deployment, would i have to create mutplie install msi packages with different sylink.xml files? is the only was to define what components are installed via GPO us using the MST file as Jeff described?
PS - Jeff, i couldnt open the 2nd link you posted - Access denied.
Thanks.
