Not getting DNS from DHCP server

[seedubya]

Hi all

SBS 2003 network, single NIC (I inherited it), router is default gateway and DHCP/DNS handled by server. Client PCs are suddenly not getting a dns server address when they renew their DHCP lease. Everything else comes down fine, but no DNS server address.

Result is that I get an IP address, can ping and browse internally and externally by IP but not by FQDN. If I set the DNS manually on each client everything works great but it's not ideal.

Anyone any ideas?

TIA

Are you sure that dns service is up and running on that server machine.

If you go to this site:

and enter the domain with the domain like:

ns1.whatever.com:53

and hit go, does it respond.

I dont know if the DHCP server will simply send the dns info or if it checks the dns server before giving that info to the dhcp client, but try the above first if you can.

I have to assume you have your DHCP set up correctly on the server and your services are running. I don't know what sort of router this is, but perhaps it's set up incorrectly and is also trying to do DHCP.

Thanks for the replies Guys. Problem now solved. Somehow, the DNS server entry had gone missing from the dhcp scope options.... Like most mysterious computer things I suspect user intervention.
