RE: i5 DNS server - replacing PC host table entries -- MIDRANGE-L

In your example, you could create a zone for ourheadqtrs.com that specifies which dns servers to forwarded requests to. You would specify the existing name servers for ourheadqtrs.com, and then forward requests to the someapp.ourheadqtrs.com domain to your own dns server. This would be served by a second zone with a host record for the someapp.ourheadqtrs.com domain. I haven't used the System I dns server, but it seems that this should be achievable.

I'm a little rusty on DNS, but somebody correct me if I'm wrong....

The problem I see is that Jon wants http://someapp.ourheadqtrs.com to be resolved by the i5 DNS while
at the same time anything else to the ourheadqtrs.com would be resolved normally by his ISPs DNS
servers.

If he adds an ourheadqtrs.com zone to his i5, won't his i5 resolve everything for ourheadqtrs.com?

IIRC, there are two other options:
--Preload the URL's of the selected apps into your i5 DNS server cache.

-- Create Alias records in your domain for the apps. Thus, you're users would be using
http://someapp.ourdivision.com to access the apps. Hopefully, your corporate apps weren't written
with a hardcoded domain. Still, you might have issues if the apps cross servers.

We are running about 10 primary zones. You can have all the zones you
want, within reason. Basically when your client performs a DNS query,
your DNS server looks at the URL for the ZONE, if found, the host.

www.domain.com would be zone of domain.com and host of www. If you
don't want anyone going to an external web site such as microsoft.com,
you can add that zone to your DNS server. With no host, they will never
be able to reach microsoft.com, unless they change their IP config to a
different DNS server.

Chris,

Thanks for the response and yes, you are correct about the client's
DHCP config.

I suppose my question could have been worded more clearly as "I can't
seem to find a clear explanation of the implications of configuring
multiple primary zones." If I do so, will it kill anything that
currently is running?
