We have staff that use Citrix for remote access. They are connecting to the desktops they use while at the office.
If they log off the station instead of disconnect, they can log in at the station.
If they disconnect and then try to log on locally , the screen stays black and they can not log in until we log them out.
Any ideas?

Where are they logging in from (it sounds so confusing) ??

Any reason you are allowing users to disconnect instead of logging off ?

What does the above mean ??

They are logging in from home taking over their desktop at the office.
When they disconnect from Citrix from home it leaves the screen black on the physical desktop.

Let me know if you ever figure this out. We’ve got the exact same problem.

I’m pretty sure that we also can’t RDP into the workstation when they get into this state.

We’ve found it can sometimes be temporarily addressed with a graphics driver update, but it seems to always come back.

I’d love to impose session limits, but… Architects… :person_shrugging:

We do have session limits on our VDA’s but not on workstations.
I have 2 users that can disconnect remote then log in locally. Compared profiles and GPO’s and note no differences.
Frustrating.

The frustrating thing about Citrix is sometimes issues remain for years.

According to Citrix (with no recent update) the cause is “still under investigation” and the workaround is to “just hit CTRL-Alt-Del twice within 10 seconds to unlock the screen”.

That worked in my testing will have staff give it a try.

Just to be sure we are talking about Citrix VDI (using Win11 on a Citrix virtual desktop on servers) ?

Are you using GPO or Citrix composer for policy ?

  • Is there a disconnect timeout ? By right you can set time limit to logoff disconnected sessions like 5 min.
  • Did you set to allow reconnection from different “host” ? There were some updates recently that had issues as part of security, it was disabled to prevent someone else from hijacking a VDI session when user is AFK
  • for VDI session, did you disable wallpaper (set to 0 or black), disable screensaver & power saving mode like turn off screen (sometimes it screw things up)

They log in from home. They disconnect from home to come into the office instead of logging off of there workstation. They did not get disconnected they disconnect the session.

They have a black screen on there computer when they get to the office. Remember they were logged in from home and disconnected.

This is not a VDI session this is connecting to a physical Windows 11 workstation. (Windows 11 Pro)

spiceuser-5rdc’s post has an answer that is a workaround for the issue.
