VPN issues

[Guest]

Heres the situacion, i have a W2k3 server in Spain running an aplication in
SQL, whe have more than 200 offices that access this server an run the
aplication over VPN in a MPLS network and is working fine, in Portugal we
have other offices that access also by VPN but over xDSL and this used to
work until we install SP1 on W2k3 Server. Spains continues to work, but none
of the offices in Portugal can work with the applications, the VPN is working
fine, we access mail to but the application crashes.
Does anyone have any ideas? It would be apretiated!
