DHCP is not giving out correct DNS address

My SBS server was 192.168.0.11 but now is 192.168.0.10.  For some reason when a DHCP client renews an IP address the DHCP is handing out the wrong DNS address of 192.168.0.11 and it should be 192.168.0.10.  Any suggestions would be great.

Where in the DHCP console?  I went into manage authorized servers and my old DC was still showing up with the IP 192.168.0.10 so I removed both of the authorized servers, the new one included, and reauthorized the correct to reflect the correct DHCP server.  However the clients are still receiving the DNS server as 192.168.0.11.

In the dhcp console, into Server Options - you need find a option "006 DNS Servers" and Edit with the address of the new dns server.

OK... I added it into the server options section under name servers along with my ISP's name servers too.  Still a no go.

if you have a windows domain not push the isp dns . just push AD DNS.
into a client push:  
ipconfig /release  (release actual ip configuration)
ipconfig /renew (renew the configuration)
ipconfig (show new configuration)
and paste results
