Windows 10 TCP connection limit on TMG Server


  • Good Day

    We have first Windows 10 test client in our environment. We are also using TMG Server. Have now the problem that Windows 10 opens a lot of TCP Connections to the tmg Server. this does result that i can not open http pages with any Browser. TMG logs that max number of tcp connection per minute was reached (Limit is set to 900 at the moment)

    if i check with netstat on the Win10 client i see A LOT of connections to the TMG server similar like this:


    I know that Win10 is calling home to MS much more than win7 or win8. is there any TMG recommedation about TCP and HTTP Limits per Minute? I have already disabled as much calling home as i can...

    Thanks in advance

  • Hi Thomas

    Hmm i don't remember in details because we do not have TMG anymore. As far as i remember, we disabled a lot of those pre-installed Apps and i increased the TCP Limits.

    Best Regards
