Remote Desktop Unable to Connect

Hello,

I have a computer running Windows 7 x64.  It is a member of a domain using Active Directory.  When trying to access it using Remote Desktop I am getting the generic:

"Remote Desktop can't connect to the remote computer for one of the 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
..."

I have "Allowed connections from computer running any version of remote desktop"
I have completely disabled windows firewall as the computer is behind a sonicwall firewall.  I have also made sure the remote desktop services are all running.  I also disabled the antivirus, although I don't think this is an issue because the other computers I remote into are all running the same antivirus.

I am trying to connect from another computer on the same network so it should not be going through the sonicwall. I have made sure I have the correct name of the computer and even tried using the ip address.  I can see the computer on the network.

There are several other computers on the network I remote into and it works fine.  And I have tried to remote into it using several different computers, including the server.  

FYI: I don't think it matters, but the server is running Windows Server 2008 R2.

Thank You

Check your user rights assignments and listening port.

Under the user rights assignments Remote Desktop users are allowed, and there is no one under the Deny log through remote desktop services.  

I attached a photo of the listening ports.

I just checked for updates.  There are only three optional updates needed for our printer.  Service Pack 1 is installed.

Did you say you could remote into it from other computers?

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\
fDenyTSConnection

is that set to 0?

No, I cannot remote into it from any computer on the network.  I can remote into other computers on the network.

Also, I do not have the registry directory:

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\
fDenyTSConnection

I do not have the: fDenyTSConnection folder

Is it running any antivirus software that might be blocking RDP connectivity using its own firewall component?

And, when you say same network, the two hosts are on the same subnet?

No on the antivirus, I have it completely disabled.  And yes, they are on the same subnet.

That's bizarre. With the firewall allowance of RDC, re-enable the firewall. By the way, how did you disable the firewall? I think that Windows 7 might ignore requests if the firewall service is stopped.

Also, if enabled, you should be able to run a netstat -a from the command line and see that your device is listening on port 3389.

I think I found the problem.  The computer does not seem to be listening on port 3389.  So how do I add that?

Restart the RDP service.

Also, check in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber for the assigned port number.
