If you have tried many thing other people suggest like rebooting, reloading hardware and re-installing the VPN or dial in connection, you still get the same problem. I will suggest to check the router settings and make sure TCP Port 1723, IP Protocol 47 (GRE) are opened.

Microsoft dial up networking errors, 721 is a remote PPP peer is not responding. My question is.... Is this an ISP problem, in this case Bellsouth.net or something in the computer that needs to be addressed? classicsoftware10-04-2002, 10:36 PMYou need to post more information about your system. For example if you have XP and an HP computer this may apply to you Click here (http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q318009&) 196610-04-2002, 11:11 PMThanks for the response. It is an upgrade to Win XP but not an HP. When I had the machine last weekend, I had it connecting with my ISP and dialing long distance to connect with her number in TN. It worked period. Now the only other difference is she took it back to TN and is attempting to dial from her location. I suspect somthing wrong at her location. Just looking for suggestions. I maintain that if it worked out of state at my location in KY and nothing changed, then it should work when she dial her number in TN. Very confusing.

You can over-ride the default DUN properties by unchecking the "use Area Code and dialing properties" check box .. and then .. type in the exact code plus number that you would normally dial manually into the "Telephone Number Box". 196610-05-2002, 10:09 AMThanks for the response.......but I removed my connection plus we made her default dial up her number without the one and area code. I did make a one and area code connection at one point so that I could dial her number long distance to see if it worked. It did. That number, the one with the one and area code is still listed but not as default. We can certainly have her remove it and see what happens. 196610-06-2002, 12:12 AMTime to put this thread to bed, she called early this PM and stated t
