Apologies in advance if this has been asked, but I've been spending the best part of 2 weeks trying to find an answer to this issue online.
I have a Windows Server 2012 R2 server running Remote Desktop Services in a Quick Start deployment for Session-based (as opposed to Virtual machine-based). This has been running perfectly fine for over a year without issues, but since a couple of weeks ago
1 user can't launch applications properly. When trying to log in it just sits loading the app. If I click Details, it displays the Windows Server 2012 R2 login process with the username and underneath it says "Preparing Windows" and the dotted circle
has stopped moving.
When this first happened I restarted the server and removed the local profile but they were still unable to load the application. In the end I created them a new account and transferred their files across to their new profile. That was on 19/06/18 and today
they have the exact same problem which I have resolved for them in the same way - creating yet another account for them and transferring their files.
I can't keep creating a new account for this user every 6-10 days or so. This issue has happened on 18/06, 29/06, 03/07 and today (09/07).
So far I have managed to rule out our AV products as tried to log on with them disabled which experienced the same issue.
I have also managed to rule out GPO settings on the user account (even though the same settings are applied to 200+ accounts which are working fine) by moving the user account in AD to a new OU and disabling inheritance before logging back on and getting
the same issue.
I can't find anything in the Windows Event Logs and the server processes hundreds of connections without issues, nor can I find anything concrete online aside from issues when renaming admin accounts or removing temporary profiles (these are not even being
created but are not forbidden from doing so) or dead forum posts where no-one has answered in over 3 years or try adding the site to Trusted Sites Zone. I even ran sfc /scannow on my server and it found nothing to fix.
I know the issue must be with the profile as I can load applications perfectly fine as my account from my PC but when I try as the user having issues I see the same as they do. Nothing changes on my PC between it loading fine for me and not for them so please
don't say there is something on my PC or in my IE/computer policy setup.
The user is getting more and more frustrated about the issue and I am getting to my wits end trying to solve it. Any assistance would be heartily received.
