VNC Crashes when I...

By JOVE ·
The Setup:

I have a Windows 2000 Server box that has a static IP and connection provided by an ISP accross the street from my office. This box acts as a NAT Router using the Win 2k Server Routing and remote access snap in. This network has 3 machines in it. Each machine has its own IP being routed by the NAT Router.

The Problem:

Whenever I connect to any of the machines (From a remote location) or I connect to a machine (Remotely) from one of the machines at this office, after a minuteor 2, VNC (Virtual Network Computing from AT&T Reasearch Labs) CRASHES. In the windows client it gives me no error, but with the JAVA client it gives me different errors. One of the common errors the JAVA client displays is "Framebuffer update rectangle too large: 5620x33604 at (257,1290)".

Thats about it. I hope someone can help. Thanks.

Probable cause could be due to ISP using some kind of Firewall or you've enabled IP filtering on your win2K box.
I rekon the procedure you're doing is ok, but cause is due to eirehr the VNC.exe file or a firewall stopping it. Try using the latest VNC or update it with a patch if available.

Several suggestions on this one.

1. Make sure your NAT router has static port mappings, so they stay open all the time and are not triggered dynamically from inside your LAN.

2. Try using the vnc client instead on the java webserver.

3. Use the terminal server in W2K server to access both the server and a VNC seesion to the other systems, then you do not need to rely on the ports staying open in the router or firewall. You can D/L the TSWEB interface from MS for free, it is really quite good. It is a web interface for your terminal services, and is encrypted.

Take Care.

I'll will make sure those static port mappings, but I have used the vnc client and get the same problem. I will try that trick with terminal services. I use both terminal services in client and web form now, I think its good too.

Thanks for yourhelp.
