Limited number of TCP clients on Windows 2008 R2 VM

    Question

  • Hi

    I have a TCP (GPRS) windows service running on a Windows 2008 Server R2 on a virtual machine. When the service is started around 1500-1980 TCP connections are made by client devices on a port. Once this limit is reached other connections are refused. I have added the registry entry MaxUserPort and set it to maximum without any increase. I have set the following keys as well:

    TcpNumConnections - 16777214
    TcpTimedWaitDelay - 60
    TcpWindowSize - TcpWindowSize
    KeepAliveTime - 30
    MaxFreeTcbs - 10000
    MaxHashTableSize - 10000

    I am still limited to the same value of 1500-1980.

    Are there any other settings that I need to change or could tis be an issue with it being a VM?

    Thanks in advance
