Unable to Remote Desktop on to upgraded Windows Server 2008 R2 Standard
Posted on 2011-02-17
I am having trouble connecting to one of our server 2008 machines.
I have just upgraded it from 2003 to Server 2008 R2 Standard. Before the upgrade it was working fine. After it just doesn't accept any connections with the error:
This computer can't connect to the remote computer.
Try connecting again. If the problem continues, contact the owner of the remote computer or you rnetwork administrator.
If I try to connect from a different subnet (allowed through firewall) then I get this error:
Remote Desktop cannot connect to the remote computer for one of these reasons:
1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network
Make sure the remote computer is turned on and connection to the network, and that remote access is enabled.
I've got the Firewall off for all connections, and the service is running.
the allow/deny log on policies are not defined by group policy. We have another 2008 fresh build on the same domain which works fine.
I can RDP from the machine no problem, just looks like incomming connections are not working.
The remote settings are set to "Allow connections from computers running any version of Remote Desktop (less secure).
The only odd thing here is that I can't change it to 'Don't allow connections to this computer, whereas I can on another 2008 machine on the same domain.... I wanted to try setting it off, rebooting and turning it on again just to see.
I wonder if something has to be done after a 2003 machine is upgraded to 2008 before it starts working again? or is there anything else I can check/try?
Anyone got any ideas?
