Step by Step for vpn using l2tp and preshared secret on a single Windows 2003 Server?

Can anyone point me to a step-by-step guide for setting up a client to
server VPN connection from XP to Windows Server 2003, using L2TP (not
PPTP), a preshared secret (not a certificate), using a single Windows
2003 server (not 5 servers, as in the Microsoft lab!)?

Both the server and the XP are behind natting routers, so I know it'll
need Nat Traversal.
