In our Windows SBS 2011 network with about a ten Windows 10 1803 client machines, we cannot connect to one of them using Remote Desktop Connection. The error is the following:
Here are the Firewall settings of the problematic PC:
Here are the Firewall settings of other clients, where the connection can be successfully established.
How do I replicate the same settings on the problematic machine?
Thanks.
Your screenshot shows that the firewall exception is only configured for Domain networks. Windows 10 1803 made it pretty difficult to check the currently active connection profile, the easiest way is to do this via powershell:
You will get errors for interfaces that are not connected, you can safely ignore them. Relevant is the attribute
NetworkCategory
. If it showsDomainAuthenticated
it's seen as a domain network and the firewall exception should work. If you get a different value you either have to fix the network detection, or configure the firewall to allow RDP on other profiles.The second thing to check, is if remote connections are allowed at all. Again, Windows 10 1803 made it difficult to find the dialog for this. The easiest way is to just run
sysdm.cpl
. (You can do this right from the powershell, or from the run dialog, it doesn't matter).Open the
Remote
tab and check if theRemote Desktop
section allows connections.Using RemoteDesktopConnection with the machine IP worked. So we investigated inside the Windows Server
DNS Manager
and discovered that the IP used was assigned to a different machine name. Deleting one record and changing the IP address in the correct machine name resolved the issue.Just to recap, the machine name and the network IP address did not refer to the same PC inside the
DNS Manager
.
