We're part of the same group (it was yours truly who brought up the original topic).
The thing is we can't really control what machines we get. Sometime it's XP and other times it's 2K. Some times we are lucky and the XP machines have been updated to the previous update. It doesn't look like we'll be getting Vista or W-7 licenses in the near future. The machines couldn't run it anyway.
In addition to the Windows updates we also have firewall, anti-virus, and anti-spyware. We also install a ZIP package. It used to be Winzip but we found 7-zip does more things. 7-zip installs directly from the net. The idea was we could knock off 45min - 1 hour per machine installation. The connection to the net gets pretty slow sometimes. That's another issue beyond our control.

The thing is we are "lightweights" when it comes to how to install this sort of thing. The reason I suggested Ubuntu server is because it's available and it is a very quick install. I have an hour at the end of the day to do extra things around the lab so I figured we could do it a little at a time.
We don't actually have a web server. I mention it because previous discussion suggested it. The machine we have at the moment is a single FreeNAS box. We have hardware ready to go. Just no idea how to proceed.

Again, we are "lightweights". The more directions the better.

Here is our current setup...
AC Router <--> CLL Hub <--> Various machines
We don't control the AC Router. We can put in requests but they are having problems with Barracuda at the moment so it will be quite a while before they can help out.
My thoughts are if we can make the whole process transparent to the machines being installed/repaired it would save us a bunch of time. To do this I figured we'd need a router between the incoming connection and the hub. OTOH, if the machine were on the other side of the hub we'd end up having to configure the machines and restore them when we were done.
This is what *I* think we'll have to do...
AC Router <--> CLL Router/Squid <--> CLL Hub <--> Various machines
I don't know enough about Squid to know if we can get rid of the router part of the machine then have it sit between the AC Router and our machines. Our machines are generally set up for DHCP so my concern would be where we get the IPs from.

Bear in mind this may or may not last a while. Given the games M$ seems to be playing with licenses it may come down to Linux (and old Macs) or nothing. AFAIC, that would be fine. Unfortunately the short sighted behaviour of many employers means unless we give out M$ machines the clients are mostly ignored. It would be very hard to justify coming up with money to pay someone to install it for us (I don't get paid and I'm the senior volunteer - I don't think the supervisor gets paid either). I think I could persuade them to buy you a lunch at Subway though... :-)
