VPN via c2800 using XP client

[f2b]

This is driving me crazy.
I set up VPDN on the c2800 (with help from this forum) and worked a treat with encryption.
Now after several weeks it will not connect unless data encryption is unticked on the XP client.
It actually verifies the connection ok but fails to register on the network. Error 742. "The remote computer does not support the required data encryption type".
I can't see why this is. Cisco confg below (IP address x'd out).

TIA...Ski

Just wondered if anybody has any ideas.
