VNC Server on Windows Server 2003 as service.
vncviewer.exe Viewer on XP Pro
This has happened on several servers. Had originally been reasonaably reliable.
While connected and in use the viewer suddenly closes.
Attempting to reconnect: "Unable to determine protocol version."
Restarting the service on remote server does not fix it.
Subsequent attempts to connect: "Failed to connect to server"
Rebooting server fixes it.
Found this error in the logs of one server:
Faulting application winvnc.exe, version 184.108.40.206, faulting module winvnc.exe, version 220.127.116.11, fault address 0x0001a45a.
Thanks for any suggestions.
