We previously had a VPN server to server working no problems. The new SP1 was installed last night, and I'm now getting this error appearing in the event log :- Source: RemoteAccess EventID: 20111 A Demand Dial connection to the remote interface MBWP_SI on port VPN4-8 was successfully initiated but failed to complete successfully because of the following error: The connection attempt failed because your computer and the remote computer could not agree on PPP control protocols. As you can probably see, I'm using PPP rather than IPSEC Please help Paul Crisp Snr network support analyst Metal Bulletin plc ------------------------------------------------------------------------------ ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
