Hi guys!
I hope you can help me. A customer needs to see the other domain servers in network area of the Windows Explorer for some Siemens legacy software. Following some other articles that should be very easy, but I'm experiencing a problem: The servers in the domain can't see each other, at least in the network area of the explorer, they can only see them self. Except for one of the 5 servers, which can see the other 4 members. I compared the settings a couple times and the only visible difference was the already activated SMBv1 feature, but even after reactivating that old stuff on 2 other domain members doesn't made it somehow better.
We are talking about 5 Windows Server 2016 VMs, which are in the same subnet and can access each other without problems.
What I've done so far:
- Ensured, that DNS, Function Discovery (both services), SSDP and UPnP services are running
- also read something about WinRM - it's active too
- Re-enabled SMBv1 and made sure, that Computer Browser is running (shouldn't be necessary, but it doesn't works anyway)
- activated network discovery in network and sharing center
- also set "Turn on Mapper I/O (LLTDIO) driver" and "Turn on Responder (RSPNDR) driver" to enabled for domain via GPO
- triplechecked, that Windows Firewall is turned off
- reset network settings on one server via "netsh int ip reset" and "netsh winsock reset"
- several server restarts
I really don't know what's the problem, I hope somebody can help!
Best Regards
Jonathan
