Event ID 1035 — Terminal Server Listener Availability
I had an issue on the terminal server stack on one of my Citrix XenApp 6.5 servers recently.
The event log ID was 1035 and the message was Terminal Server listener stack was down
The OS was Windows Server 2008 R2 so unlike the previous versions of Windows, I was unable to rebuild the listener. It shows the reliance that ICA now has on RDP even though the protocols are supposed to be “independant”.
Initially I tried the compulsory server reboot and shockingly, it didn’t make any differencem Below are some of the areas I looked at, turns out that disabling and re-enabling worked for me but some more checks and options below.
Some quick checks that helped me below
1. Can you RDP to the server
2. Can you telnet the server on 3389
3. Have you checked the listener in the TCP stack – netstat –a
Some possible fixes
1. Try to disable and re-enable the remote desktop connections ..
a) On the terminal server, start the System Tool - Start, Run, Control Panel
b) Under Tasks, click Remote Settings.
c) In System Properties > Remote tab, select the Don’t allow connections to this computer option.
d) Repeat as above and re-enable the connections
2. Restart the Terminal Services Service
3. You can manually recreate the Listener by restoring the following registry key from another server that works fine (use the registry at your own risk).
HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\ICA-TCP 4. As a last resort it may be an issue with Remote Desktop Services and the windows Feature may need re-installing. However you will also have to reinstall Citrix XenApp.
