Stations can see server but server can't see stations

[WindChaser]

Hi folks,

This happened out of nowhere: today, all of a sudden, I can't see the network stations when I click on Network from the server. The stations can see the server and everything is working fine from their end. I checked Network Discovery on the server and it is ON. I also checked the SSDP Discover and UPnP Device Host services on the server and they're running.

Does anyone have any idea what's going on?

Thanks!

I'd definitely look at firewall's and which firewall profile is in use.
