A customer has a RDS for that 6 remote Users access all day. Occassionally, and more recently becoming fairly frequent, the Users call and state their icons look odd. I perfrom a direct Remote Control from the RDS and although my dekstop and profile are fine the remote Users have resolution and colors similar to 640x480 @ 32bit, almost like being in Safe Mode, when it is actually set to 1920x1080. The Users cannot change the resolution and when checking it shows 1920x1090, greyed out.
Me logging into the same server at the same time looks fine to me and the two networks I test from are fine. All Users with this issue are on the same physical network in a different office. If the Users drop the connection and re-log in, the issue is gone for a while, then will intermittently return. It usually appears after they minimize the connection to perform some work on their local desktop.
I thought it may be a potential issue of over heating of the RDS Server, which would show funky video issues. However, this is a VM on VMWare and the host has no issues, nor do the other VMs on this Host machine, nor are any issues seen when locally connected and logged into the RDS by me or anyone else on the RDS local network.
My questions is about the RD connection. If bandwidth drops due to overutilization or other network speed issue can the Users' sessions change resolution and color, such as dynamically based on connection speed?
Other ideas to look at for this scenario would be helpful.
