I'm looking to have 2 DHCP servers (one controlling a set of scopes and the
2nd controlling another set of scopes). Both DHCP servers will be issuing
IPs. Is it possible to have ADS server have 2 Network Boot Services running
at the same time to accomodate both DHCP servers?

It's not possible to have two NBS services for the same ADS server. NBS is
made up of 3 services: PXE Service, Deployment Agent Builder service and TFTP
service. It's not possible to have multiple instances of these for the same
ADS server.
Can you tell me why you want to use Two DHCP servers for ADS?
We have ADS here servicing 6 subnets in different buildings, all serviced by
the same DHCP server which is installed on the ADS server. The hardware is a
4x CPU box with 4Gb RAM, hardware RAID. So far this works great.

Thanks for the reply,

I am looking into a dual DHCP setup to protect against a hardware failure on
the servers. I manage over 14000 servers and need a way to ensure that the
DHCP server is always online. So i have all the scopes on both DHCP servers;
however, i split between both servers on the management of the scopes. So in
the active active state, if one of the DHCP servers fail (hardware-wise),
then the second server will have the authority to issue addresses for all
clients.

Well, i guess i will need to install a second ADS server and share the IDS
service for images...

Boy i wish there was another option.
