Re: Strange VPN Access Problema) check the name resolution of the dyndns name via the connection it's working, and the one it's not
b) do a ping test to said name from both connections, also run a traceroute. Make sure your traffic is able to make it to it, or however far it goes.
c) do a telnet to said dyndns name on port 1723 from both connections... does it show OPEN, or open a blank black screen from window's cmd prompt?
d) grab the full 800-error and post it up here. Also try running it thru your search engine of choice. Never heard this one off the top of my head, but ANY sort of specific error message is ALWAYS helpful for troubleshooting.
Can't tell you where'd Windows would keep the VPN logs, you may again have to do some knocking around on the internet for this information.

Great! Exactly what I needed.
I can't ping the DYNDNS server on the failing connection. A traceroute produces the following:
Tracing route to *******.kicks-ass.org [174.65.14*.***] over a maximum of 30 hops:
1 2 ms 1 ms 1 ms 192.168.1.254 2 22 ms 23 ms 21 ms 99-71-140-3 .lightspeed.sndgca.sbcglobal.net [99.71.140.3] 3 * * * Request timed out. 4 * * * Request timed out. 5 * * * Request timed out. 6 20 ms 23 ms 23 ms 12.83.70.141 ... 13 41 ms 41 ms 41 ms 68.6.11.186 14 42 ms 40 ms 43 ms dt1xcmtk03-gex030000.sd.sd.cox.net [68.6.11.185] 15 * * * Request timed out. (time out repeated another 10 or so times...)
Telnet connection failed on 1723.
Error 800: The remote connection was not made because the attempted VPN tunnels failed. The VPN server might be unreachable. If this connection is attempting to use an L2TP/IPsec tunnel, the security parmaeters required for IPsec negotiation might not be configured properly.
I had done quit a bit of research on Error 800 and tried a dozen different solutions to no avail. Hence the "start at the beginning" approach I am trying now. One intriguing solution was that the ISP suddenly started blocking GRE for one user, but isn't that a server side issue? Should I check with my ISP (AT&T) to see if they are doing this at my home?
I can't test the working connection right now because the one I was using is no longer up. I can try from my neighbor at work when I get back there later in the day.
Thanks for the great help!
