Remote Desktop stopped working after Windows Update

2003 enterprise with Sp1 and all updates.

I can no longer connect via RDP to this server from the LAN.  When I run netstat -an | find /i "listening" the port is there.  The firewall is turned off.

Here's the kicker:  when I telnet to server 3389, I am just returned a quick command prompt.  It doesn't get through, but it doesn't return an error.

Any ideas?

Is this a Terminal Server or just an administrative RDC connection?


If it is just the admin RDC, My suggestion is to disable Remote Connections then reenable them.  And even reboot (if possible).


If that doesn't work, can you send me the list of the latest updates that were applied?

It's a Terminal Server but I also use RDC on it.  I tried exactly what you said and am awaiting the reboot. I also removed Microsoft Baseline Security Analyzer b/c it errors out 4 times when the server starts up.  Just guessing....

"when I telnet to server 3389, I am just returned a quick command prompt."  This sounds like a successful Telnet test to me..  

So you type

telnet servername 3389 <enter>

then the screen flashes and a "_" is displayed... then you click any key and your are returned to the cmd prompt?  if so, this means you are successful in your telnet test.


what error do you get when you try to RDP to the server.?

No, it just automatically cycles back to the command prompt.  In other words, I end up at the command prompt again immediately.

Maybe the TS server ran out of licenses?  what error do you get when you try to RDP to it?


Also try this:

mstsc.exe /v servername  /console  <enter>


This will give you console access and should allow you in even if the TS licenses are not available.

The fix...

Turned off Remote Desktop.  Uninstalled MBSA.  Rebooted  - "Gold Jerry...gold!"

Like the rest of you, I hate to reboot servers during production - but sometimes it's the easiest fix!

Hmm.. interesting.. I don't think MSBA had anything to do with it... although when something throws errors like that, you never know!!

This is a common issue people have directly after updating and rebooting.  I suspect (as I have been trying to determine the exact cause) that pending file operations from the update that occur during the next reboot interfere with the TS service enough that it doesn't work.

A second reboot after patching is the only way to fix this that I have been able to determine.

The only viable answer was provided - until MS fixes this I haven't seen anything else that will bring it back to life.
