Saswata,
Very interesting, took a cue from Chuck and attached the following, does any
of this look familiar?
WHAT MICROSOFT SAYS:
For a device running Windows CE 3.0, if this attempt to locate a DHCP server
fails, the DHCP client will auto configure the stack with a selected IP
address from the Microsoft-reserved class B network 169.254.0.0 with the
subnet mask 255.255.0.0. This process is called Automatic IP (Auto IP). Auto
IP is enabled by default. To disable Auto IP, update the AutoCfg registry
key. The DHCP client will test, using a gratuitous ARP, to be sure that the
IP address the client has chosen is not already in use. If the address is in
use, the client selects another IP address. The client repeats this
selection process for up to ten addresses. Once the DHCP client has selected
an address that is verifiably not in use, the client configures the
interface with this address. The client continues to check for a DHCP server
in the background every 5 minutes, or according to the interval specified by
the AutoInterval registry key. If a DHCP server is found, the auto
configuration information is abandoned and the configuration offered by the
DHCP server is used instead.
Note If the Windows CE client determines that a DHCP server is available,
Windows CE checks if the IP address offered by the server is on the same
subnet. If the address is on the same subnet, Windows CE requests that it
use the automatically configured IP address. This feature prevents
application sessions from being stopped unnecessarily.
AND WHAT IANA SAYS:
IP block lookup for 169.254.0.0
whois -h whois.arin.net 169.254.0.0

Subject: RE: A question
I believe the 169.250.0.0 is a Microsoft reserved address. Microsoft, if
memory serves, uses it in conjunction with their automatic network
configuration A search of the RFC's did not reveal anything. A search of
ARIN whois indicated that the block itself is assigned to "linklocal"
Microsoft claims it is theirs

Subject: A question
Hi Networker
I have couple of questions.
1. We recently received a router preconfigured from
one of our client. The moment we connect the router to
our network, all of our PC in our internal network got
a message about IP conflict with another IP address
which is not our internal IP address. We use
10.210.X.X as our internal IP and the conflicting IP
was 169.254.X.X. We use DHCP server internally. This
router was connected to our network through Sonicwall
Firewall which disallows all the incoming traffic. So,
we removed the router and everything worked fine. So,
my question is "Is there a DHCP server in the router?"
2. How should I connect my PC to the console. I have
the console cables with me. I am using Windows NT
server. I tried to connect the cable to the com2 and
when I tries to use the Hyper terminal it took most of
the processor time. So please help me out.
Somebody please help me. I have to finish this work by
the end of the day.
TIA.
Saswata
