I have Windows 2003 Server configured to be VPN server. I succeed connecting from Windows 2000 as client, but I get 721 error when trying to connect from Windows XP.

Please help, thank you
 
I have the Same setup and I have the same problem.

I have a windows XP machine that doesn't seem to be able to VPN to our servers. If I have that same person use the windows 2000 machine it works fine. I was able to get the XP machine to connect 1 time but I have no clue why it worked. Any ideas?

It connects.. Verify's username and password then fails with 721 error.
 
Hey guys.

I have a similar problem but I have no idea if Win2k clients would work as we only have Win XP.

The really irritating thing is that Win XP clients are able to VPN to our old Win2k Server which we want to decommision but they experience the same Error 721 problem you have when they attempt to connect to Win2k3

Kind regards

Phil.

I used to have a artcile talking about this case but can't find it. Basically, if you can access VPN from win98 and W2k but not XP, it could be the hardware issue. Check the router firmware. or check these pages for addionatl information,
