Are there any errors in the event log indicating there may be another DHCP server somewhere?

Hi, we are migrating to a totally new infrastructure, consisting of new servers on 3.x network. Current users are on 2.x subnet. <br />
Earlier we were able to assign a user a static ip address and he was able to move his pc to the new domain and ad.<br />
<br />
During work today in moving the kit out, the old dhcp on the old domain (the old and new forests were trusted) was switched off before it could be unauthorised.<br />
<br />
I have authorised the new dhcp with scope on 3.x only, and its not assigning an adress to the users even if connected directly to the switch.<br />
<br />
Is the infrastructure I have still looking for the old dhcp server for ips?<br />
<br />
If so how to get it to now use new scope/dhcp? Can I just add 2.x scope to new one for now?<br />
<br />
New AD is 2008, old was 2003<br />

DHCP Issue

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).
