96x1 handset Dhcp Issue

[IPmonkey]

Had a few problems on an install today with the 96x1 not getting dhcp address from the IP500.
IP500 is set to dhcp server 'only for Avaya phones' & SBS2011 server is on the same network for the PC's dhcp.
Have no problems with the 16xx series phones or the 96xx handsets getting the correct dhcp addresses but the 96x1's are always grabbed by the SBS2011 dhcp. site is not using vlans..
I have managed to statically address the phones as only a few today but wondered if any ideas on why its happening or how to get around the above with a 242 scope option telling the phone to fcuk off to the IP500 dhcp server without using vlans for a site with 20 phones?

You can also make the server ignore dhcp requests for certain devices I believe, we found out by accident when our SBS would only issue to Windows devices and not iPhones, Avaya handsets or blackberries etc

Cheers for that Andy, looks like I may need to setup some dhcp filters and deny certain mac addresses and see how it goes from there.

IPMoney, you can but you need to use VLANS ofcourse
I have a simple doc for sevrer 2003 but this is amost the same on a server 2008 so probably also on the SBS2011.


BAZINGA!

I'm not insane, my mother had me tested!

Hi tlpeter, thanks please send over the doc to botch billy @ bt in ter net dot com and I will take a gander.
The problem with this from an engineering point of view is that this site & most small sites have out-sourced IT companies, so this proves to be a pain in the arse in getting access to servers when things like vlans need setting up & they almost always dont want us messing around with them.
Cheers

That is the hard part when you do not get the cooperation you need.
