Vista Issue - Wired vs. Wireless

[John Miller]

I have a rather strange problem that I hope someone can help me with. This
is a general DCHP issue as I am not sure what software the server is
running.

 

We have several Vista clients that are not able to get an IP address when
trying to connect wirelessly. They connect just fine when wired. The DHCP
server is the same machine. I have done packet captures for both wired and
wireless. I can see the DHCPREQUEST go to the server and I can see the
DHCPOFFER come from the server. The server logs confirm the request and
offer. In each case (wired and wireless) the DHCPOFFER looks identical. The
only difference is that when wired the computer responds to the DHCPOFFER
and does not respond when wireless. I have not seen any correlation with the
brand of adapter, but that could be because we have not looked for one.

 

The only way we have found to resolve this issue is to do the Vista registry
fix to turn off the broadcast flag in the DHCPREQUEST for the wireless
adapter (KB 928233). While this will work, it means that any student who
wants to connect to the wireless AND has Vista will need to bring their
computer to our office to have the fix implemented.

 

Has anyone ever seen this issue and found another way to resolve it?

 

Thanks - John
