ZoneAlarm was completely removed (no change in behavior) Also to confirm, RealVNC was running as a service and no screen saver enabled. RealVNC seems to have had no issues interacting with desktop. Client functioned perfectly for a short period of time (1-5 minutes). Longer, if I didn't actually do anything on the remote machine and just let the connection sit idle. Also, a number of other things were tried. Final resolution: I ended up uninstalling RealVNC and installing TightVNC. Was able to connect from Win XP systems and remote control Win 2000 system with no issues. So, it looke like TightVNC will be my solution. Thanks to everyone for all the suggestions and assistance.
