disable "Estimated network bandwidth on one of the connections" check

    Question

  • I have several Windows clients that hang at applying computer settings when starting up. All computers that show this behavior have 2 network adapters. One is the physical adapter another is a virtual adapter created by 3rd party software. Virtual Network adapter always stays enabled (even if you disable it, it comes right back to the enabled state) and has an APIPA address assigned to it. The OS sees the adapter in connected state and attempts to estimate the network bandwidth on that connection, but since no traffic is being passed through on this link it's  forced to wait for the time out, which causes the delay. So the question is, how do you exclude a specific network adapter from being checked for bandwidth at the OS start up?

    Thanks

  • Hello,

    You can Change Interface Metric in registry via GPP.

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<GUID>
    Name: InterfaceMetric
    Type: REG_DWORD
    Value Data: Number from 1 to 9999

    Regards

  • That made no difference with the start up times. Looks like bandwidth is being checked on all adapters regardless of the metric value

    >>One is the physical adapter another is a virtual adapter created by 3rd party software. Virtual Network adapter always stays enabled (even if you disable it, it comes right back to the enabled state

    Based on the description, it's recommended that we contact the vendor support of the software to see if they can help disable the virtual adapter or provide some suggestions regarding the situation.

    Best regards,
