I have a machine on my LAN (call it MACHINE-NAME) that is set in workgroup WORKGROUP. I believe this is the standard now for Windows 10, it's a pretty recent install and I haven't done any particular modification of the networking/services/etc. All the other Windows machines on my network show up in the Explorer Network tab except for this one. Wireshark reports that it responds to Windows Discovery Service messages with this as part of the reply for the wsdp:Relationship/wsdp:Host/pub:Computer
key:
<pub:Computer>
MACHINE-NAME/NotJoined
</pub:Computer>
The docs here seem to suggest that this means the machine believes it is no domain joined or part of a workgroup, but the System section of the Control Panel suggests this is not true.
Both the Function Discovery Provider Host and Publication services are running on the machine. It can access all other machines on the network correctly via \\PC-NAME\. I can access this machine from all other machines via \\MACHINE-NAME\, it just doesn't populate in the Network node like every other machine on the network (these machines do report OTHER-MACHINE/Workgroup:WORKGROUP
in WDS messages).
Any ideas why this machine reports this way?
