Hi Experts,

I am facing a problem with a Windows 2008 R2 server.
Suddently I am no longer able to access it via RDP.

The problem sounds much like this http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2008/Q_27812381.html
but After checking and trying the solution here it brings me nowhere.

The problem started some toime ago, but could be resolved by rebooting the server, but not any more.

I have checked, at RDP-service is running
RDP is set to port 3389 and all LAN adapters
No obvious errors in eventlog
Turning Firewall off does not change anything.

Trying to connect from the server itself with RDP og by telnet to port 3389 are not possible.

I have tryed using localhost or the actual IP (from the server itself).

Anyone with a solution, before I go mad?

Is RDP listening on port port 3389?

You can check this using the steps below:

Open a command prompt and execute the command netstat -ano |findstr :3389
Make a note of the PID that is being shown against the port 3389
Go to the task manager and on the Processes tab locate the PID and corresponding Image name. This would usually be svchost.exe
Right click on the image name and use the option Go to Services
This should take you to Remote Desktop Services (TermService)

In case you do not see the above or see some other service then we have a problem. Post the results on what you find.

Assuming you are connecting internal these are some troubleshooting tips (some you may have done already):

- disable all firewall(public/domain/home)
- check in system settings > remote connection (middle option) is checked, to allow
- dns issue? try ip instead of the dns name
- are there any other devices (firewall/vlan/other) that can be blocking something?
- antivirus, local firewall (software) is blocking something?

Check:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber

is this a decimal value of 3389

HKLM\System\CurrentControlSet\Control\Terminal Server\fDenyTSConnections = 0

check and if all fails or you have adjusted anything, reboot...

Good luck!

I believe that you have made sure that in the System Properties the Remote Desktop feature is enabled.

In the services is the Remote Desktop Services (TermService) in the Started state?

Did you check the System event logs for any events being logged that is related to Remote Desktop Services (TermService)?

Have you tried deleting and recreating the RDP listener?
The following articles can be used for this:

Except for checking "HKLM\System\CurrentControlSet\Control\Terminal Server\fDenyTSConnections = 0" I have tried all this before, without luck
This did not help aither.

Unless something is logged in the event viewer, it will be very difficult to find out what caused the issue.

Happy to help :-)
