RRAS: The VPN server may be unreachable, or security parameters may not be configured properly for this connection

Hi,

We had setup RRAS to connect our networks. The RRAS computer tries to
establish a connection another RRAS computer, but this fails since a couple
of days. We are not aware that we have changed anything. The error message
is:

Event Type: Error
Event Source: RemoteAccess
Event ID: 20111
Description:
A Demand Dial connection to the remote interface xxx on port VPNx-x was
successfully initiated but failed to complete successfully because of the
following error: Unable to establish the VPN connection. The VPN server may
be unreachable, or security parameters may not be configured properly for
this connection.

How can we troublehoot this?

Thanks in advance for any feedback
Greg
