Re: RDP Connections - Freeze or Reconnect

The client has disconnected the router from the network and internal users accessing the TS over RDP are still reconnecting frequently. Nothing logged in event viewer for both server and on client end.

If I look at the licence manager for TS I see

Windows 2003 - Terminal Serer Per User CAL
Type=Open
Total=20
Available=20
Issued=0

Not sure if this should be showing a number of issued licences. I have re-actived the licences and the error has not been reported in the event log since doing this. Does this look right to you?

Every user accessing the terminal server via RDP is seeing the session reconnect. It reconnects in seconds and the screen is back to where it was when it left it. Nothing is logged anywhere suggesting a problem. I am going to run a ping -t to see if any packets are being lost over the LAN. May imply it is an issue with the switch as everything else has been replaced.

Any ideas where I go next?

There is nothing logged in the event viewer about this. A few odd warnings but nothing that I haven't seen before.

I will run another windows update tonight and I have just asked the customer to turn off the ADSL router to see if this improves the connection with the internal users.

Yesterday we put a new APC-UPS on the server and installed the latest version of powerchute. I have since removed UPS and software thinking this was the problem. What did happen yesterday which may be related is that the server lost power from the UPS because the UPS connections on the back are really poor and the power cable just fell out. This mean't the server shutdown without warning. I have reset winsock thinking this might be corrupted. Also now using a second NIC but with no improvements. Could it be the switch?

One thing that I have noticed is that if I go directly to the server console and run RDP to 127.0.0.1 - it is stable.

This problem is getting more bizzare by the day and is now driving me crazy!!!

I thought this problem was resolved but today it would appear it has got much worse. I went out to the site today and all was well until all of the internal terminal users started getting a 'reconnecting to session' windows when they were logged onto the terminal server. It was reconnecting very frequently (every 2 minutes or so). Internal Users have never experienced this in all the 5 years that they have been running the server/ I left site thinking I had fixed the issue by replacing the Network cable. I noticed that the network connection had a red x on the server and would then reconnect intermittently. To be sure I plugged a new cable into a different ethernet port on the server. This seemed to work.

I got home and logged onto the terminal server with my Vista laptop. The RDP session keeps reconnecting but it drops the connection at 3 seconds past the minute everytime. 10:13:03, 10:14:03, 10:15:03 etc. Thinking this was an issue with Vista, I tried RDP connection from my other XP laptop. Same type of thing happens.

This is an interesting issue. Please post follow ups for future
reference.

Is there anything in any of the Event Logs?


I then used my Vista laptop from home to logon to another PC (lets say computer Z - Windows XP) using VNC which is in a remote location. From computer Z I logged into the Terminal Server with RDP. Therefore connecting to the terminal server with a different internet connection. This was stable and didn't reconnect.

I am not sure what this means exactly but could it rule out the theory that the ADSL line / Router in the Terminal Server building is the problem?

This could rule out the ADSL and router but VNC may be compensating
for the bad connection where as RDP is just killing it immediately.


Today I also notice that the TS is issuing temporary licences. The licences were installed and activated 5 years ago. I will need to fix this but I don't know why this has all of a sudden stopped working.

Do you use User or Device Licenses?

What is the status of your license server? Anything unusual there?


If anyone can save me from going mad... please HELP!!

I am trying to stick with hardware because that is the easiest
place to look (IMO).

Do you have an extra ADSL router that you could test with?

Are there multiple NIC's in the server? If so could you use the
second one if it is not in use already?

Has the server been updated with the latest Windows Updates and
NIC drivers?

Did this start when some software or hardware was updated/upgraded?

I am having a really frustrating issue with RDP connecting to a Windows 2003 SP2 Server. For several years the Terminal Server has been working well but just recently remote users have been complaining that the RDP session frequently lock up or reconnects with a big red x in the top right hand corner of the screen. It is happening so frequently that accessing the terminal server remotely is becoming unusable. I have seen this before and it happens very occassionally. LAN users access the terminal server with RDP without issue. This makes me believe it has something to do with the Router or ADSL Line.

I have upgraded the router firmware to the latest version
Applied all of the latest updates to windows
Updated network drivers etc
Rebooted server
Changed MTU settings

Nothing seems to be making any improvements.

Does anyone have any ideas how I can troubleshoot this further. Workstations are a mixture of XP sp2 and Vista Sp1

Does the Router from the ADSL line go into the same network
switch that the LAN users are on?

If so and the LAN users are fine, I would suspect the ADSL line.
