using ISP for secondary DNS

Hi All,
I have a Windows 2003 network with 2 servers.  THe domain controller also acts as the primary DNS server for my network.  My question is should I use the ISP DNS server as the secondary DNS entry?  Or should I just leave it blank.  I know that domain controllers should point to themselves.  I would think that pointing the secondary DNS address to an outside DNS Server would just complicate the event viewer in case of a DNS failure.

You should definitely NOT do that. Any domain relies on DNS to resolve the domain resources, including finding a DC, and your ISP knows exactly nothing about your domain.
Only use your internal DNS server that is authoritative for your AD domain, and let this server forward request to your ISP. The forwarders section is the only place in your domain where external DNS servers should be listed.

That is what I thought!.  I was not sure how (if at all) administrators were using the secondary DNS.

Thanks.
