Slightly worrying issue here. I've deployed some printers via group policy on our domain. All servers are 2008 R2. Locally on the LAN (10.0.0.0/24), they work fine and the printers are added. These are for the Domain admins so far.
We allowed the group policy settings to propagate over the VPN connection between our site and our other site (10.45.191.0/24). It's over a 10/10 vpn so it takes around an hour or so. Anyway, we tried two days later to log in to the terminal services on the other site with the same username and the printers were not added.
Could this be due to a firewall setting at the other site that is blocking the printers being added? Port 445 is open between ourselves and the other site, so is 9100. So I'm just wondering whether this is firewall related or whether it's actually routing related?
