You should check the VPN server if Setup encryption on the VPN server.

The sever is configured with

ipSec

L2tp/Ipsec

the client is win2k pro sp4.....

The remote vpn will work with pptp no problems but not with the encription

would you know how to add the shared key on the win2k client without a vpn
client?

cheers

in this case, you may try to change Type of VPN server to L2TP instead of Automatic. To do this, go to the VPN properties>Networking. Please post back with the result.
