I normally have a problem forgetting to set the default password. Is there a way I can do it through Terminal Services?, like importing a reg string, or tricking it out some how? anyone?

To: [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] Hello, I am running winVNC v3.3.3 V9 Service on 3 windows 2000 service pack 2 computer's. I have one in my office and two at a customers site. I connect to my customers network via LAN modem. Both of my customers machines run in 256 color mode. When I connect to one of my customers machines, to see the application they are running, the screen looks fine except the colors are all wrong. Like what should be black is gray, and what should be red is blue and what should be green is orange. I tried restricting pixels to 8 bit, I tried all the different encoding methods, and I tried changing my monitor colors to 256 and true color. None of these fixed my problem. There must be some setting that I forgot to set because it works fine at other customer's sites. Please Help!!! Chris __________________________________________________ Do You Yahoo!?

When you say "lock the server" below do you mean logging off as a given user? If so this should be fixed by running VNC as a service as well. If not I am not sure what the problem might be. John S.

Then, out of nowwhere, the connection is closed and you can just reconnect and all appears to be normal, except for the closed connection? If so, then it is sure to be a network related problem. IT's a wild guess but I think somewhere on the line a connection is dropped and vnc misses a handshake and drops too. Is this a steady network or is it an internet connection? Check with your network admin.

I have experienced the same problems with my XP machines in the past. I am not sure of the exact cause, but I believe it has to do with the encoding algorithms. I use TightVNC, and the problem only seemed to occur when I was using Tight encoding. Once I changed my viewer defaults to Hextile, the XP server would remain stable.

VNC is installed in Service mode, and is set to run Automatically. When the screen is at the "Press Ctrl-Alt-Delete to Log In" prompt, VNC cannot connect. The service is running, but VNC cannot connect. This happens when I reboot the computer. It also happens when I simply log off. For example... I reboot the computer, and I cannot connect with VNC until I manually log the system in from the console. I connect to the system by VNC, and choose "Log Out"... VNC disconnects itself. I am running VNC successfully on a number of NT 4.0 Servers, Win9x workstations, and Windows XP workstations. This Windows 2000 Server is the only system that is having this problem. Any ideas....?

Most machines, specially servers only start the service/deamon/... after the remote party starts talking to the port. You will see as soon as you start using the port: start a telnet to the port and see what you get back. On the other hand, just use it and in case of problems, use an other port. > > <snip> > >> In the viewer I entered 192.168.100.127:-5820 as per the > >> docn but the Win98SE keeps getting an GPF. > > > > Try (2^16 - 5820) or (2^32 - 5820) for portnumbers. > > You have a working, not-firewall connection: try this port > change on > > this > > machine to see if your setup works from the vnc site. > > > > Interestingly enough when I run VNC on the 98SE either as an > app or as a > service and then check the properties I see that the display number > shown is 4,294,961,476. > This turns out to be 2^32 - 5819.

Then reproduce that in the target location. Debug tip: To see at which (rfb) port the vncviewer realy runs, try to find the vncwebserver at the same machine and check the html source. Specially if you change the port or display in the registry, you (and most likely your calculator!) can easily make calculation mistakes using those large numbers.

Then I run a script exporting the DISPLAY to the Xvnc display (export DISPLAY=:1) and starting some programs with: xterm -e programA & xterm -e programB & xterm -e programC & The problem I have now is that without running the vncviewer only the first program is running (e.g. programA)?! From the next programs (programB and C) I see only the xterms in the process listing (ps -u user) but the programs itself are not running. If I start the vncviewer after a while I can see sn the output (to the standard output) that the first program is working during the whole time but the other programs just start when the vncviewer is starting. Who knows what happens here and how I can manage to start all the programs immediately? Any help is very appreciated.
