Blank usernames on the Users tab of Task Manager


18171-blank-usernames.png



We have a Hyper-V virtualized remote desktop server farm with eight remote desktop servers. On occasion, a server will have users with blank usernames on the Users tab of Task Manager. Once you see one of them show up, more blank usernames will start showing up throughout the day. The problem is that the server starts to slow down after the first user with no username appears and eventually when several more blank usernames appear, no one will be able to remote to that remote desktop server. The only way to get rid of these users is to kill off the individual running processes because you can't log them off or disconnect the session (this does not fix the slow down issue). Eventually the server will need to be restarted to fully resolve this issue. When one server has this issue, it will slow down new users connecting to the gateway server until you remove that server from the list of servers that users can connect to.

Does anyone know why blank usernames appear in the users tab or what is actually causing this slow down issue?

Thank You,

Brian

Hi,
Have you patched your RDS system fully with Windows Update and Hotfix? In general, update/hotfix is helpful for resolving some known issues and improving the performance.
Also ending the terminal service in Task Manager and restart it to check.
Best Regards,
Carl

They are fully updated as of July since our patch week for August hasn't started yet. I don't know of any specific hotfixes for this issue, so if you've seen some, please let me know.

Hi,
Thank you for your reply. '
I checked the Windows Server 2012 update history, also didn't find specific hotfix. But I consider that install August update firstly may be choice.
Also have you tried to stop and restart of the Terminal Services service?
Disable security software temporarily.
We also could run command “DISM.exe /Online /Cleanup-image /Restorehealth” and “sfc /scannow” as administrator to repair corrupted system file.
Best Regards,
Carl

  • We will install the August updates, but this has been happening for a couple years.

  • We have stopped and started the service, rebooted the server, taken the server out of play and added it back to the Gateway server group. Some of those things fix the missing account name issue, but then more comes back again in a week or two. We're trying to find a way to stop this issue from happening at all. We haven't found a rhyme or reason for why it happens, but server performance really degrades when it does.

  • We have tried disabling security software and even had this issue on servers before security software is installed.

  • This is happening on all servers that are part of the farm. Over the last 2 years we have had 4 different servers in the farm and all of them get this issue. The newest server was added 7 months ago and it started having these issues a few weeks after it was setup. It was brand new out of the box so it shouldn't have corrupted files.

@BrianHenry-1792

Were you ever able to figure out what was causing it in your farm?
We're having the same problem in ours. Comes and goes, very erratically.
