Your XP client wants to use L2TP/IPsec but your IPCop server is configured
for plain IPsec (i.e. without L2TP). You have to decide which one you want
to use:

- plain IPsec with Marcus Mueller's IPSEC.EXE utility
- plain IPsec with a commercial third-party IPsec client such as NCP,
   Greenbow or SoftRemote
- L2TP/IPsec

L2TP/IPsec is not supported out of the box by IPCop. It is still in
development. See also:
