Yesterday I had perfect Remote Desktop access to all the computers on my network. This morning, for apparently no reason, I am unable to connect to one of the computers on the network. The target computer is running Windows 10 and installed an update overnight. If I can find no solution to this then I will have to try restoring from yesterday's system image, but hoping to find another solution.
I am able to view files in the target computer by going through network
on any of the other computers on the network; it is just the Remote Desktop that will not connect.
I am able to Remote Desktop connect to other desktops from the target computer, but not to the target computer from any of the other computers on the network.
I get the same problem whether trying to access the target computer either from inside or outside the network. All other computers on the network have no problems.
I have tried running the windows troubleshooter for remote connections but it finds no problems.
I have checked all the port numbers and firewall permissions; the target computer is on port 3388 so I have made firewall exceptions for this port - regardless, it was working fine yesterday with the same configuration so I am at a loss.
What was the update? – Dave – 2016-06-17T09:58:23.933
@Dave it was KB3163018. I have tried uninstalling the update but no change. – Matthew – 2016-06-17T16:14:15.310
with "the target computer is on port 3388" you mean you have checked with
netstat -an | findstr 3388
on the target that it is listening and withtelnet targetIP 3388
from another PC that the port is available? – Zina – 2016-06-17T22:04:11.140I just reinitialized Windows 10 and the problem has gone away now. Not sure what the cause was but this seems to have been the solution. – Matthew – 2016-06-17T23:00:17.770
