21/02/03 I have the symptoms as described underneath. today I have discovred something new: As we where in a training on 5 machines on which vnc service was running I noticed the following:
The whole morning all worked fine. As we came back from lunch some macines were blacked out others had a screen with vertical dotted lines. All machines where frozen. After restart it happend again after about an hour and a half. This was when everybody was typing, so it can not be a screensaver/power saving issue. My question now is: Should the client not be idle and stay Idle ? As I have installed the VNC server on my PC which was not even logged on, I am sure there was no such request from the VNCserver. Is it possible that some kind of other trafic on the network triggers a remote control request. I checked DHCP but this renewal was not due for another 5 days. ______________________________________________________ [Laurent Appels] 20/02/2003 > I have several PC's that run DOS a application alomost continiously. > Running under W98 SE. > If the client is installed ADn the application is run full screen, the > machine freezes to a black screen, seemingly at random times, > but on a regular basis.
