Problem Resloved!

	Thanks to all who offered assistance.  The problem was due to packet
fragmenting through the vpn.  The resolution was to reduce the MTU size on
the windows me server to 1362.

Thanks again to everyone.

(1)	I have tried 4.0b with the same result.

(2)	The winme machine can connect to the xp box.  This just keeps getting
stranger.

Thanks again,

Blake

Blake:
	Two ideas:

(1) try it with VNC version 4.0b on the WinXP machine
(2) VNC into the WinME machine, and from there VNC into the WinXP
    machine. Does that work at all?

	Good luck!
