VPN error 721 on connection A, but fine on connection B

setup:
server A is in Florida
server B is in Lousianna
laptop behind linksys router on DSl at home in Lousianna
all other computers used to test VPN connections to both sites located in both Lousianna, and florida

OK, an employees laptop can connect to server A fine, but gets error 721 when trying to connect to server B (since i can VPN to other servers im assuming its not a firewall issue of allowing PPTP or anything). Everyone else can connect to both server A & B with no problem so its not a firewall issue blocking teraffic from the servers. I used the same user/pass in all situations as well. Any help is greatly appriciated. if you need any more info just post and i will get back asap.

There must be something different in the setup of the one laptop that cannot connect to B..
You might have to do some digging to find out what this user has loaded that others have not - don't believe the old story "nothing!" "just this firewall" "just this cute toolbar that puts smiley faces on everything" etc...

well she had installed SP2 and then noticed this problem, i have rolled back to SP1 with no success. i re-intsalled tcp/ip and even repaired the tcp/ip stack.

Les Moore

Did it ever work pre-SP2?
You might have to resort to a drastic re-install of XP Sp1...

ASKER

yes it worked prior to the install of SP2

Les Moore

OK, well, at least we have narrowed down the culprit...
Try re-installing SP2 and then checking through the firewall settings...
It's like any other firewall software. Once its on, un-installing it just makes things worse..

but, why would the laptop be able to VPN to other servers and not this specific one.. that seems to rule out possible firewall interference). every other computer i tested can connect to this serverjust fine except this laptop.

ok, i figured it out. i just set her user account on the small business server to give her a static IP on connect. apparently her ip range at home was interferring with the ip range at the office. thanks for all the help :)

Mods: is there a way i can keep this question open for others to view so that it can be helpfull to somebody? i dont care about getting the points back. thanks.
