Yes. Try doing what I suggested. Get the winpcap drivers, and ethereal. Capture the traffic, ideally on both sides, and look at it in ethereal.

That's how I discovered that the VPN layer kept up, but the VNC connection did not.

Ideally onboth sides of the connection.One time, I had a severely wacky problem with TCP connections dying. Turnedout that one of the routers was corrupting the packets.Even if is not something as odd as that, seeing the traffic can make a bigdifference.Jordan> -----Original Message-----> From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On> Behalf Of [EMAIL PROTECTED]> Sent: Thursday, February 13, 2003 12:33 PM> To: [EMAIL PROTECTED]> Subject: Client disconnects repeatedly over VPN>>> I have a WinVNC server v3.3.3.R9 running on Win2k (SP2), and a> remote vncviewer client, running on Win2k (SP2), connecting to> the server over VPN.
