VPN client gets error 741 (local computer does not support the required data encryption type). Only way to get around the error is to select "no encryption" on the radius server remote access policy (then the connection works).

The server is a ISA 2004 server accepting L2TP/IPSEC clients with pre-shared key. Client is a Windows XP SP1 client.

Any idea?

I beleive this is an encryption problem! Possibly the local machine (Client) OS is not supporting encryption?

Please let me know how you get on.
