Make sure both ends of the VPN tunnel are compatible to each other.
As Paul may have found, IPSec and PPP don't play nice together.

    Absotively!
    If the remote wants IPSec and local wants PPP, they argue for a minute and 
grump their separate ways..

      You're correct Jim ( Doh! should have tried that first )

      No it doesn't so must be something else. It seems that the remote office 
is experimenting with IPSec for a connection to an external business, could 
this affect the VPN ?

        Hi Paul, 

            Does the problem go away if you remove SP1A?
            You're right; SP1A shouldn't affect your VPN settings.  I'd be very 
surprised if it did.

          Could be coincidence, but seems strange. 

          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
