Windows NT 4 Domain??

Ok, here it is... We have an NT 4 Domain with some Win 2000 and XP Prof
clients. Some of the 2K and XP clients have been manually configured in
gpedit.msc to point to our SUS server for updates. What we would like to do
is find an easy way to configure the rest of them to point to our SUS server
as well. I first thought about login scripts that simply add the appropriate
registry keys and values. But I am not sure the results would be uniform. I
then wondered if you could take the wuau.adm file and import it into the old
Windows NT 4 System Policy editor. We currently use it to do simple things
like hide Network Neighborhood and those settings get applied to all machines
on our domain including NT, XP and 2000. If I could import that wuau.adm
file into the System policy editor I think the results would be much better.
I expect our NT machines (what few we have left on the domain) will ignore
those settings and our XP and 2K machines should work ok. Anybody have any
ideas on this on maybe done it already?
