Terminal Server/Remote Desktop Black Spots/Splotches

Posted on 2007-08-01
Last Modified: 2013-11-21
I am running a WIndows Standard 2003 R2 Server with Terminal Services as a Virtual Machine using VM Ware. Users are connecting to the Terminal Server with Wyse XP embedded thin-clients via RDP V6. Users are reporting black splotches appearing after working for a couple of hours. Logging off and back on or closing the Remote Desktop Connection and reconnecting resolves the problem. Has any one ever seen this behavior on a Terminal Server session before?

Tune the RDP client for the LAN, and perhaps uncheck some of the boxes on the Experience tab.

It sounds like there is congestion on the LAN segment.  

You could always look at some network performance data from something like MFRC.

For the record, last post in the following link implies this is a known issue with the Wyse units. Have you tried contacting them, or updating the firmware?

Tuning the RDP client worked, it was a combo of having it set to 32-bit instead of 16-bit and Bitmap caching. Thanks

For our organization, just disabling the Bitmap caching seems to work.
