Re: Home PC's and DNS addresses



Just so I'm not tagged as a complete slacker, I did configure one of my
workstations with a static IP address and the following DNS servers:

(the second two addresses are my ISP's DNS servers)

192.168.1.2
67.87.72.130
67.87.77.130

Then, I shut down the SBS.

The PC w/ these DNS servers was able to continue to access the internet even
though the 192.168.1.2 DNS server was unavailable.

Ideally, I'd like the DHCP server in SBS to dole out it's address, and my
ISP's addresses as DNS entries for all workstations on the local network.

I'm not too concerned about the DHCP server being unavailable, since most of
the other systems are on all the time and the possibility of their DHCP
address expiring during a period of SBS downtime would be small.

I will explore a solution to this question (thanks for the suggestion), and
maybe the answer will be of help to small network admins.

Best regards,

Bill

The SBS DNS/DHCP should be set up automatically. If you need to fix it, then
you can do two things;

a) run the Fix My Network wizard
b) download and run the SBS 2008 Best Practices Analyser

Where there are issues, you'll be provided with explanations and help by
these tools.

SBS needs to be the *only* DNS server, it will process local requests and
pass non-local requests on to the internet where appropriate via forwarding.
Having additional DNS servers listed will cause issues, as you don't want
clients going to DNS server that can't possibly resolve the requests for
internal resources. That will only cause delays and malfunctions.

SBS needs to be the DHCP server, if at all possible, to ensure the client
computers are configured correctly.

Also a good answer.

But... and please forgive my quip, neither response has furthered my SBS
DHCP/DNS understanding or expertise...

I'd definitely use the SBS DHCP; if it's ever taken down, it's a simple
matter to enable the DHCP on the router and renew the leases on the
remaining boxes.

Not a bad idea, I was just being lazy I guess.

From a geek perspective, it would be cool if the SBS could issue DNS
addresses that don't result in it being a critical component for
workgroup
internet access. If it were easy to configure this behavior, I would
choose
that over manually configuring my 8 other workstations, or setting up a
secondary network.

Thanks for the suggestion though.

Why not connect the home pcs that are not on the domain, directly to
the
router with static private IPs...or if you want DHCP on the home
pcs...set up a second router, WAN side with static IP in the range of
the
router the SBS box is connected to, and let the LAN side do dhcp for
the
home pcs

My SBS2008 system is being used at home for educational purposes,
and I
would
like to let it be the DHCP server for all of my home PC's, but there
are
times when the server is down for whatever reason.

One problem this poses is that the single DNS address my SBS doles
out
via
DHCP is it's address.

I would like the SBS to use it's address as the first DNS address
issued,
but also issue my ISP's DNS addresses for the 2nd/3rd entries on
each
workstation. My thinking is, and it could be wrong, that if my SBS
is
unavailable, the workstations would then use the secondary/tertiary
addresses
to access internet resources.

Does this sound right? And if so, what would I need to do to
configure
this
behavior on the SBS DHCP server?

Thanks
