Sorry for a delayed reply on this. I typed out a reply yesterday but lost it due to a random hardware issue 🙁
I think you’re correct that this is potentially the same issue. I’m not sure why, but our folks are reporting that the disconnect issue seems to be mainly when they are using Microsoft Office apps; specifically, Word & Excel.
I’ve gathered log files from the terminals and the Windows PCoIP agent that are having the disconnect issue but haven’t been able to find anything helpful 🙁
I had a report this morning that one person got disconnected while trying to do a copy paste into Excel, so I’ve disabled PCoIP clipboard redirection via GPO in hopes that this might help the disconnect issue.
We were having a similar issue with the time zone. I was able to solve this by group policy with setting the time zone (via registry key) and disabling time zone redirection (in the same group policy).
Not sure if your logon script for updating the time zone sets the registry key, but if not perhaps give this a try.
Here’s the page I used for setting the time zone via GPO with a registry key.
