Unrecoverable failure

[Galaxiom]

Version 1.05
VNC Server on Windows Server 2003 as service.
vncviewer.exe Viewer on XP Pro
MS Authentication
MSRC4Plugin-122.dsm plugin

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 1.0.90.0, faulting module winvnc.exe, version 1.0.90.0, fault address 0x0001a45a.

Thanks for any suggestions.
