VPN error 800

i have set up a vpn connection on windows 2000 server. now the thing is one client connects and he has no problem, the other client connects and gets a vpn error 800. the vpn client they are using is winxp vpn connection.
i do not think my router has outdated firmware else the other client too would not get in.
any ideas?

Hi.
What are the firewall setups you've got going on?? (ie: What firewalls on what machines?)

It would seem that the client getting this error has a firewall, which is disabling NetBIOS or/and VPN.

I hope that helps.

Really?  :o\

I think that it would be best to temporarily uninstall the firewalls, completely.. Make sure that there aren't any other built in firewalls on... Like, with Windows XP, it has a bulit in Firewall that causes people so many problems (because many people are unaware of it)..
Just make sure of this.

Also, is this VPN setup over the internet??

If so, can the client who's having problems connecting PING the server that it's trying to connect to??
(This can be done, by openning command prompt (start > run > "cmd" > ok), and typing:
   ping servername
Then hitting enter).
