Re: Setting up a 2nd DNS server on SBS network

Tech-Archive recommends: Fix windows errors by optimizing your registry

I don't do a SBS reboot in the middle of the day because I really want to do
that. I have to reboot of the server because of Windows & ScanMail updates
requirement and people are still working late because they need Internet
access to watch webcasts for focus group etc and that's why I need to set up
a secondary DNS server. They might not need email access at the time but
anytime there is no internet access its like the roof had collapsed. I
don't want to wait until they are done with their work until 9 pm and reboot
the SBS server. I don't want to reboot the server either while at home for
problems that might arise sometime.

Thank you for pointing out about PDC/BDC in AD as peers. I never knew about
this chemistry.

You thru me off when you mention making "If you set up your secondary DC
properly, with
DNS, and make it a global catalog server, you can then add this server's
IP address to your clients' IP config as a secondary DNS server (via DHCP,
one hopes)."

I thought the primary DC is supposed to be the Master of all. Why would I
have to make BDC as the Global Catalog server. To my understand, GC server
is an index mechanism that keeps info of every objects on AD network
correct. When you have SBS install that is the master of all is not that
true? If not, how do I make the BDC as the GC server as you have mentioned
and as the backup DNS server. BTW, BDC is a windows 2000 server, do you
think SBS 2003 likes sharing its DNS information with this version of OS?

Thanks,
Helen

Note that there's no such thing as a PDC/BDC in Active Directory. All DCs
are peers. And yes, I would expect plenty of crying phone calls if you're
rebooting your SBS box in the middle of the work day, and not just because
of DNS issues - that shouldn't be happening at all. If you're having major
problems on the SBS box which require regular reboots, you should address
those immediately. If you post in here with the details I am sure someone
can help you out.

which is
where DNS is host. So do i need to set a secondary DNS on the BDC or
can I install it on another member server?

If you have an additional DC already, it should be set up with
AD-integrated DNS (this is normally done when you set it up but you can do
it later). Do not set up DNS on a member server, and do not set up a
secondary DNS zone. AD relies heavily on a properly working DNS structure
and if you mess this up your domain will be in bad shape. Be careful!

Can you also answer my original questions as well.

Sure - but you hadn't explained your question or your situation well
enough for me to do that before. If you set up your secondary DC properly,
with DNS, and make it a global catalog server, you can then add this
server's IP address to your clients' IP config as a secondary DNS server
(via DHCP, one hopes).



Thank you,

There is a Backup DC on the network

Good morning,

I want to set up a second DNS server on SBS network again but I
can't remember what I have to watch out for on SBS network. Its is
going to be a secondary DNS server on the 2nd server correct? Do i
enter the ip address of the primary DNS server in the property tab
of the 2nd server?
Thanks,
Helen

You should only do this if you're adding an additional DC &
AD-integrated DNS server for redunancy.

If that's not the case, you should probably explain what it is you're
trying to accomplish.....
