Unable to Remote Desktop to Windows 2003 Server

Source
Do a remote shutdown "shutdown /r /t 10 /m \\computername"
I have seen this problem after patching here recently. and either I have to reboot the machine at the console or I have to do the remote shutdown indicated previously.
-------------------------------------------------
Do this:
- ping the RD host by its IP address to ensure that it is correct.
- ping the RD host by its name to ensure that it can be resolved.
- run telnet to check if the RD port is open, e.g.
telnet MyServer 3389  

How to Enable Remote Desktop Connection



------------------------------------------------
You are running wireshark on the 2003 server, yes? That will tell you that
the tcp packets are arriving on the interface you selected destined for port
3389 and their content, nothing more.
  On the client it says unable to connect to RDP.
This indicates that RDP is either not running on the server, not listening
on tcp port 3389, not configured to accept connections from the client, or
that a firewall is blocking. You state that firewall is disabled, so that
narrows it to 3 potential causes.
Short of rebuilding the server are there any options or troubleshooting steps i should take?
If it's listening on port 3389 then you know that it's just not allowing
access to that client. If it's listening on a different port then you know
that piece of information as well. I use the following free application to
get familiar with my machine:
