Hi, I am having an odd DHCP issue and have probably missed something obvious or fundamental here. The scenario is an SBS 2003 Server being scaled out to a full Server 2003 Domain environment. I am not using the transition pack as the SBS Server is old hardware that I am going to phase out / DCPROMO out rather than scale up. So I currently have a SBS 2003 Device with Exchange 2003. 2 x Server 2003 DCs all FSMO and GC roles are still on the SBS box for now and no other DCs are GCs. Additionally I have a Member Server running Exchange 2007 Co existing with the Exchange 2003 Server. This is all in a single AD Domain. I have 2 routers on the network. I noticed that the SBS 2003 Server DHCP Server stopped and an event log entry stated that another DHCP Server existed on the network. It pointed to one of the routers so I confirm that both routers had DHCP disabled and after being unable to restart the DHCP Server I uninstalled it and moved the role onto one of the other DCs. The DHCP function is now running on another DC and not the SBS. The DHCP Server Service does not stop like it did on the SBS however clients keep obtaining there IP info from another system with the IP address of one of the routers. I have switched off the router and am unable to ping it switched off so its not a case of two systems misconfigured with a single IP address however even in its powered off state clients still obtain IP from a device with the IP address of the router. I have run ipconfig /release and renew and it will still not pick up IP from the Windows DHCP Server however around 4 or 5 clients have done successfully. As you can imagine because of the DNS option I am getting some network issues. Can anyone offer some suggestion into this? Many thanks
