Yes to disable DHCP in the 7100, you simple just need to delete the LAN pool and VoIP pool from the DHCP pools section.
I assume you have a voice VLAN on your network? If it is num2, then you will need to make DHCP Option 66 on your windows server match the following:
You will also need to set the NTP option which is 42 to be the 7100 also: 10.10.20.1
This makes sure the phones have the same time as the 7100.
This article give more info:
What are your phones plugged into? Directly to 7100 or your company’s switches? How are the switch ports configured? Access or trunk ports?
What is your native VLAN number?
Yes there is a Voice Vlan and the ports are Trunked.
Here's a little breakdown of what it looks like
Vlan ID: 2
IP Address: 220.127.116.11
Primary DNS: 192.168.12.1
NTP: Server 192.168.12.1
I've set these options on windows DHCP server options and it just doesn't work. I've also followed that article that you linked. all phones connected to nv7100 ports.
If you changed the Data and voice vlan IP on the 7100, then there are additional voice settings you have to change, see step 3 and after you do that then make sure you do Step 5.

So I narrowed down the issue....
There's no communication between the Data Vlan and Voip Vlan. How would my windows server lease addresses to a subnet that it cannot communicate with? Two options are 1) setup second NIC as VLAN2 on same subnet as Voip Vlan or 2)setup firewall policies and routing on the NV7100. Since their vendor manages the NV7100, we're going to leave the phones on the Adtran, and move the Data DHCP to the Windows server.
Thanks for all of your help and replies! This was definitely a good learning curve.
What most people do is use the windows DHCP server to hand out IPs on the data network and then keep the voice DHCP pool on the 7100 for the phones. That is what we teach in class for the 7100.
