DNS server WITH Linksys router?

J

JonnieStyle

Hi all.

I got a small AD network working beautifully, and now I've wrecked it.

The school recently got ADSL and I'm trying to install it AND have the
active directory work nicely too. But here's the catch:

I can EITHER have logon nice and quick (by pointing the client DNS
settings to the server) but then they can't resolve names to IP
addresses on the internet

OR

I can have a painfully slow logon (by pointing the client DNS settings
to the router of the ISP DNS servers), and internet access works
fine...

How's the best way to fix this? What am I missing? I'm sure I can
configure the DNS server (on the domain controller) to reference
outside DNS servers, but for the life of me, nothing's working! The
logon is far too slow. What must I do?

Cheers.

All you need to do is to point the clients at the DNS
server on your LAN but you need to do one thing on your
DNS server: I assume that there is a folder that you see
under the server in the DNS Console that is labeled with
just a dot(.). This is what is preventing your DNS
server from doing Internet queries. You need to remove
that folder because it causes the server to host a root
domain and so queries stop there. I would also recommend
setting up your DNS server to forward to the DNS servers
of your ISP for security reasons. For starters, in the
DNS Console, click the View Menu and check off Advanced.
(It's possible that you won't see the above mentioned
root folder unless you do this step, but I can't
remember.) This will show the cached records that the
DNS server will get from querying your ISP's DNS servers
or from the Internet directly and it will be a way for
you to confirm that it's working. Then, in the
Properties for the server on the Forwarders tab, click
the "Enable forwarders" check box, add the IP addresses
of the ISP's DNS servers and check off the "Do not use
recursion" check box to insure that it always uses the
forwarders.

I'll give it a shot and let you know how it goes. Thanks!
