Unfortunately, I am attempting to get this working through a very tightly secured state firewall... they have ping/icmp/etc. blocked... I got them to open port 80 on a static IP for me so that I could get in at all.
But it is the latest version of tightvnc for windows running on 2000pro. You think i should try the old vnc? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Alex K.

Also - a less commonly known problem - it is possible that you are experiencing problems with a "black hole" router between the twp systems. I'm not sure how VNC responds to excess packet fragmentation, but it may be worth checking. One way to do this is (if the remote system doesn't drop ping requests) is to attempt to ping it with large packets and the non-fragment flag set. On Windows systems, here's how you would do that. If the remote system is at IP 123.123.123.123, then try: ping -l <packet-size> -f 123.123.123.123 and vary the packet size from about 200 up to 1468 or so. If you start losing contact below 1468, chances are there is a fragmentation issue between you and the server. ----- Original Message ----- From: "Patrick Linley" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, 2002-06-26 18:28 Subject: can connect only from some pc's > I finally got winvnc to work on port 80 through our firewall - I can > connect to it from some locations, but not from another location.
