Are you sure?
Any machine acquiring this address is effectively unable to communicate with
any other host on the network, unless your DHCP server is also assigning
addresses from the 169.354/16 range.
Are they so small that everything is on a single network switch?
If so, you can use NetMon or whatever network traffic capture tool you prefer
to watch for that IP address.
The MAC address will tell you what machine owns this IP.

Thank you for your replies.
That's the problem. It's a small company with a handful of computer and they
are all getting an ip address. Is there a product out there that I can use to
snif local nics?

It's actually exactly what it says.
ISA saw a packet from the network connected to the "Private (PCI)" interface
using a source IP address is not part of the Windows routing table or ISA
network configuration for that interface.
What needs to be solved is why your internal host is not getting an IP from
DHCP.

Running ISA 2004, a client of mine all of a sudden started getting the alerts
below. There were no changes done to the network routing. Can anyone shed any
light as to what would be causing this with a windows assigned ip address?
Thanks.
Log: Application
Type: Error
Event: 14147
Time: Jan 14 2008 9:33AM
Source: Microsoft Firewall
Category: None
Username: N/A
Computer:SERVERNAME
Description: This event has occurred 3 times from 09:18:04 Jan 14 2008 to
09:33:48 Jan 14 2008.
ISA Server detected routes through the network adapter Private (PCI) that do
not correlate with the network to which this network adapter belongs. When
networks are configured correctly, the IP address ranges included in each
array-level network must include all IP addresses that are routable through its
network adapters according to their routing tables. Otherwise valid packets may
be dropped as spoofed. The following ranges are included in the network's IP
address ranges but are not routable through any of the network's adapters:
169.254.0.0-169.254.255.255;. Note that this event may be generated once after
you add a route, create a remote site network, or configure Network Load
Balancing and may be safely ignored if it does not re-occur.
Regards,
Christine
