So, This is a tricky one.
I use a system where users connects via VPN to a Terminal Server on an other site. It is working fine for everybody but one user. For this user the screen is flickering/flashing/refreshing constantly and the session is unusable. It did work two days ago. No changes know by the user since then. Computer in Win10 and Server 2016
What I did is:
play around with caching, resolution, color depth (in mstsc settings) ... > same flickering erase the remote desktop cache > same flickering log with mstsc on an other server with his computer > works fine try to connect with his user on my own computer > same flickering download the other remote desktop from microsoft store > same flickering try to update network card driver, video driver > all up to date windows update > same flickering check network settings > everything is fine properly sign out the session of the user on the server > same flickering erase the user profile from the server > same flickering
Performance of the PC are all good. No overload network, ram or cpu
So I am clueless...any other ideas woudl be greatly appreciated.
