We have a LAN with several buildings connected by VPN over T1 lines. The connection is fast enough for most things but when there are updates to Flash or Adobe Reader that we push out thru the GPO it can take quite a while to install if someone reboots during the day and the workstation starts pulling the updates down. Since they are run on the computer side they kick in on a boot and you have to wait for them to finish.
Right now we have one AD/DNS server and the sysvol there is where the updates are stored. Is there a way to have that sysvol at each location (all on different subnets) so the updates are pulled down from the closest share rather than from the main one?
