Hi Greg,

As per my original post, XP firewall is turned off globally. No connections
are firewalled.

I did find the problem, and it was simple just as I thought it probably
would be. :)

Per the SOP from my employer, to set up VPN connections into their network,
the advanced TCP/IP settings box 'use default gateway on remote network' is
to be UNchecked.

Now under XP SP2, checking this box has corrected the problem. VPN now sees
all my ping, tracert, etc. requests for my employer's network and appears to
be working fine.

Not sure why the instructions are to UNcheck this box when setting up VPN.
The UNchecked box does work just fine under Win2k and XP SP1. Something
broken has now been fixed?

Since I solved the problem, I did not try your registry key below. (I think
you meant HKLM\*system*\CCS... ). Should anyone else try it.

This was a stupid problem to be sure, but I would like to see this tested
and put in the kb and/or technet where a search can find it.

Thanks again for working with me on this.
