adding router to DHCP server

I have a DHCP/DNS server 2003 that I just installed with it’s own static ip of:
192.168.100.1.
255.255.255.0

Tried adding the server to the Belking 4 port router which has an ip of : 192.168.2.1 to the lan port.

I am unable to ping or access the routers web setup page.

Disabled DHCP service but still no luck.

Any help appreciated.
