Windows RealVNC server not accepting connections

I'm running the latest Free RealVNC server in service mode on a WinXP box
and it isn't accepting any connections. I tried to connect to localhost
and I get a dialog box right away saying the connection closed
unexpectedly. I'm not prompted for a password.
The icon is in the tray saying it is running.
What do you recommend I do to troubleshoot this?
I found the log in the Windows Event Viewer. When I look at properties,
this is what I see for every attempt from localhost:
SocketManager: unknown listener event: 0
But when I try to connect from a Linux machine on the subnet, it doesn't
register anything. When I use nmap on the Linux box to look at the
Windows box, I see that port 5900 is "filtered" rather than "open".
I was able to use "vncviewer -listen" on the Linux box to receive a
connection from the VNC server on Windows. That worked but only
momentarily. It locked up almost right away and then the VNC server
crashed on Windows, including the usual Microsoft request to report the
error, which I did.
