Remote Desktop & VNC - Causing Black Graphics

Posted on 2005-05-10

I have an application that draws maps using an old technology (Zapp) running on a server.  I have noticed whenever I connect to this machine via VNC everything is fine.  However if I connect via Remote Desktop and restart my application my application just displays a black screen instead of the maps.

I am using Remote Desktop to connect to the console session so that I can use it in a similar manner to VNC i.e. mstsc -v -console

I also notice that once I close the remote desktop window, and attempt to VNC back into the server all that is displayed is a black screen (Windows desktop, I can see nothing!) and I dont appear to have any control over the server.  If I then reconnect with Remote Desktop my VNC window will become visable and I have control of the server again until that remote desktop session is dropped.  The only way I can get VNC to work correctly thereafter is to restart the server.

Any sugestions as to what is going on here ?

    I don't have first-hand experience with this problem, but having searched around, you might try running this command via Remote Desktop:

    "TSCON 0 /DEST:console"

    It will end your remote desktop session and then you will be able to VNC again, hopefully without having to restart.  As for an actual fix to the problem, the only thing I can suggest is to try and upgrade the video card driver.  Perhaps there is some kind of incompatability there.

    Good luck!
