remote printing killing rdp sessions
Posted on 2008-10-08
I have a LAN at site A with a 2003 DC and a 2003 terminal server. Users on site B connect to the terminal server at site A via an ipsec tunnel.
The problem is printing. The printers are setup and printing ok, but when a client at site B prints to a printer at site B(via a terminal session) it slows the terminal session down for other users and causes large delays. So I decided to implement qos. I have configured both routers to reserve 90% of available bandwidth to RDP traffic.
I have only implemented the qos today so I cannot say if there is an improvement yet or not. But a thought crossed my mind. Is the print job sent back to the printer using RDP? If so then using qos will have no positive effect.
However, another option would be to disable printer redirection on the terminal server configuration. I could then install the printer which is at site B on the terminal server at site A using a TCP/IP port. Therefore when user in a terminal session at site B prints, the job would be queued on the terminal server and sent back down the tunnel directly - i.e. not using RDP. So the qos rules would apply.
Am I on the right track here?
