Slow RDP Connections RRS feed

  • Question

  • I have a Server 2008 with 8 desktops in an office. No LAN issues connecting to the server. No performance issues. Only some complaints with slow internet connections.

    2 separate locations use terminal services to connect to the server. Both locations have slow refresh rates perhaps? Performance seems slow.

    Speedtest.net

    #1: D-18.29 Mbps U-.5Mbps

    #2: D-27.5Mbps U-.43Mbps

    Speakeasy:

    #1: D-31.52 Mbps U-4.27Mbps

    Xfinity:

    #1: D-31.9 Mbps U-6.01Mbps

    All pings were below 30ms. Not sure what else to test or what the issue is.

  • Hi,

    Thank you for your posting in Windows Server Forum.

    Does this issue happens for initial connection or for all RDP connections?
    What happen if you make RDP connection within same location? Have you find the same slow RDP connections issue over there?

    If you don’t find issue within same location then the cause is usually network related. 
    - Also for a test try to disable all the redirections (Driver, Printers, video, Clipboard, etc.) and check the result. 
    - Disable IPv6 in NIC setting. - Try to disable chimney, task offload and RSS by following command and then check the result.

    NETSH INT TCP SET GLOBAL CHIMNEY=DISABLED
    NETSH INT IP SET GLOBAL TASKOFFLOAD=DISABLED
    NETSH INT TCP SET GLOBAL RSS=DISABLED

    In addition to above try to edit the .RDP file and add the following line.
    enablecredsspsupport:i:0

    Hope it helps! 

    Thanks.
