One DHCP server at a time...get rid of the DHCP on the Catalyst and put your servers on static addresses or use the DC to assign them via DHCP reservations.

or put those servers on a VLAN...

Unusual IP sounds like 169.254.x.y, aka APIPA, which means that the clients cannot reach the DHCP server with the DHCP requests. <br />
You nead to either configure IP helpers in the catalyst to forward the DHCP requests to the server, configure a DHCP proxy on the client LAN, or place the DHCP server on the client LAN. <br />
If the problem is for just some clients when the rest gets correct addresses, it sounds like the DHCP scope is to small and nead to be changed to handle more addresses.

I have a new domain controller set up to run DHCP and while I can configure everything to the network using static IP for some reason it doesn't grab the correct IP address if at all. &nbsp;There is a cisco catalyst switch in between the server nic and the rest of the network. &nbsp;Its just a 14 port switch that assigns the IPs to the severs in the enclosure and four external ports. &nbsp;I have gotten unusual IPs on different subnets on some of the client computers not within range of the DHCP server.

DHCP does not automatically assign IP addresses

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).
