We have 4 computers that are exactly the same. For some reason, 2 of them stopped allowing connections via RDC using the computer's name. I can still connect using the internal IP address, but this is complicated for the end user, because they just know their computers by the actual name. In DHCP on the server the still show up with their names, and in System on the actual computers, you can see the name of the PC, so I'm trying to figure out what happened.
I don't know if a Windows update caused this or if some setting got off. I've verified the Windows Firewall settings, making sure that RDC is listed as an exception. I've review the local policies in secpol.msc and I've also reviewed the registry according to some posts I found online. I've also done a netsh int ip reset reset.log and still nothing.
