spoof attack??

Our ISA2004-Firewall shows the following message: "ISA Server detected a
spoof attack from Internet Protocol (IP) address x.x.x.x. A spoof attack
occurs when an IP address that is not reachable via the interface on which
the packet was received. If logging for dropped packets is set, you can view
details in the packet filter log."
The from-IP adress is not existing in our network. Also we see, that the
destination IP is 255.255.255.255
We have this message since three days. We can "turn it of / on" by starting
/ ending groove.
Has anyone an idea, what this could be?

When you say "by starting/ending Groove" what exactly do you mean - The
Groove client, Groove Manager Server or Groove Relay server?
