    Hello @Lars Blizard ,

    If you are prepared to generate and share some trace data then we will perhaps be able to understand what is happening. I would suggest capturing ETW events for the Microsoft-Windows-FunctionDiscovery provider and network packets.

    The Microsoft-Windows-FunctionDiscovery events show the steps taken to discover resources:


    The network packets show the actual protocol mechanisms and results:


    If you are willing to make a trace, then just let the forum know. The first piece of information that we would need is which version of PktMon you have. If the output of the command "pktmon start help" looks like that below then you have the newest version - the information is needed to correctly construct the command(s) to capture the trace data.

    pktmon start [--capture [--counters-only] [--comp <selector>] [--type <type>]
    [--pkt-size <bytes>] [--flags <mask>]]
    [--trace --provider <name> [--keywords <k>] [--level <n>] ...]
    [--file-name <name>] [--file-size <size>] [--log-mode <mode>]
    Start packet capture and event collection.
