i have a 2003 server domain setup at home and have a question about the DNS setup. in order to utilize AD i have to point the primary DNS back to the same box (the only server i have running...so it's doing it all...AD, DNS, DHCP, etc). my question is:

in order to get to external websites (via my cable modem router) i had to add my 192.168.0.1 (router) as the secondary DNS. what i am wondering is will that freak out AD at some point? i know it tries the server first...and then goes to the router when the server doesn't know what's up. i'm guessing this is ok, but i don't want to mess up my dynamic DNS entries and such that tie into AD.

why would you have to do that ? you should just be able to make a network connection as a internet gateway without a dns lookup, either forwards or reverse. The only way you would have to do that is if your router was actually working as a server, and your if your router is only connected to the server. You can do this by adding another nic in the server, and with the nic setting it to use dhcp.

I just answered this same question on another forum, so I just c&p'd it here for you.

Here's what you should have...well, with whatever IP's your using:

Notice there's nothing in the 'Alternate DNS Server' section. The only time you shoud put an IP there is if you have a BDC or you're doing split-brain DNS with another DNS server.



And then have your ISP's DNS servers IP's defined in your 'Forwarders' section, such as this:




Also, just for shits n' giggles, here's my scope options from my DHCP server MMC:

You don't need the 004 Time Server in there, unless you sync up your box with an ntp server. But the rest are pretty standard for a DC. Notice you don't send the IP of your ISP's DNS server to your clients, just the IP of your DC DNS....which is also pretty much the standard.


And yes, you'll cause your AD box total hell if it's not done that way...Trust me. And if you do it this way, you won't screw up anything like your dns entries. PM me if you want help setting it up.
