We run VNC 4.0 on our WAN, and I connect to remote machines (500 miles away) through VPN and VNC. On some servers on our network, my vnc performance is just fine. It's tolerably fast and no disconnects. On other servers on the same network, it's either extremely slow, or drops my connection very frequently.
1- Is there a way I can troubleshoot this? If I could tell my sysadmin WHY this is happening, I'm sure he could fix it, but he has better things to do than spend all day troubleshooting vnc connectivity problems.
2- Is there a better/faster/more robust tool than VNC?
3- Any idea why some servers (one in particular), would be dropping my connection, on average, twice per minute?
