Cannot Obtain IP - Windows Vista

[Guest]

I have my Windows Vista business connected to my network at work. I am unable
to get an IP other than 169.XXX.... I thought at first it maybe was a NIC or
Hardware problem, so I tried installing VISTA on two seperate PC's that use
diifferent NICS. XP works correctly on my network

When I connect vista to a cable modem it works fine.

From what I have read so far, I believe it is a problem with one of the
routers on my network backbone. I have read that Windows Vista runs TCP/IP
differently than XP. Am I right in guessing this.

If I am right I am....How do I fix this. I don't believe I should have to
change my backbone in order to install VISTA

I have run a packet sniffer and I can see the discovery, the offer, the
request and the ack, but vista never gets the IP. HELP

Err.... tcp/ip is tcp/ip if standards are followed.

My bet is that you didnt remove the tick from IPv6 and it is stuffing you
up.

You'll need to be more specific.

In the office, I have several Vista workstations that get their IP
configuration via DHCP. The DHCP server is "centralized" and is in a
different subnet - there are three routers between the Vista workstations
and the DHCP server (the local one plus two others in the path). I think
all of the routers are Cisco, but I don't know what model etc. (someone else
looks after the WAN). There were no changes made to the "backbone" to
"support Vista".

This all worked "out of the box" - no special action was required on the
Vista computers (no need to disable IPv6 as someone suggested).

if you setup static IP, can you access ping DHCP or other servers?

From my vista box, I connect to a nortel switch (not sure of model). I then
go via fibre over a vlan to another building and connect to another nortel
switch. From there I connect to a Novell Zenworks DHCP server. I can see from
the DHCP server that it is discovering the PC, and the handshakes are going
well, and i even see and ACK when I run a packet sniffer, but the PC never
gets an IP. All I get in my event log is and error that "The object already
exsists".

You've probably already tried this, but I'd go to a command prompt and do an
IPCONFIG /RELEASE and then reboot the machine. Hopefully, when it came up
it would get the new address.
