I have SBS2003 Standard and want to VPN from XP with SP2.
No problem using PPTP but cannot make it work with L2TP.

Have created certificates and deployed to workstation.
I have two NIC's in server: 192.168.16.2 and 192.168.1.7 to my router which
is using NAT. Ports are opened on router and have tried opening it
completely. NAT on router for XP workstation.

I have reproduced the first 5 messages from the log - Event Viewer -
Security. My domain is ibs.local
public IP address for XP machine is: 213.218.243.182

I have opened the ports on RRA and also enabled EAP.

I can create the VPN connection with the two machines networked on a LAN,
but strangely I cannot then map any drives.

Can you help?

Thanks,
Steve.
