Hi,

I'm setting up my SBS 2008 server and I need help configureing my DNS on my domain to point to it.

My domain is'nt registered with a microsoft partner so I need to know what DNS settings I need to enter to point everything to my server.

my domain is registered with 123-reg.co.uk.

thanks.

You still need to run the wizards in the SBS console to configure the server and internal DNS; "Connect to the Internet" and "Set Up Your Internet Address".

Externally you need to access the management console for your 123-reg.co.uk account and create the following records for DNS:
-An 'A' or Host record that points remote.YourDomain.co.uk  (assuming you accepted the default "remote") to your SBS site's WAN IP
-An MX record that points to remote.YourDomain.co.uk

You also have to configure your router to forward traffic on the following ports:
SMTP  21  incoming mail
SSL  443  OWA and RWW  
        987  RWW
PPTP 1723  VPN if used

thanks RobWill, I've ran the setup on my server and I've changed the DNS on my 123-reg account. I'm getting DNS errors when I run a DNS health check on the domain now but I'm hoping this is just because its taking time for the changes to take effect.

I'll leave it a while and try again.

It can take up to 48 hours for DNS changes to propagate over the internet, though it often completes in 6-8 hours.

hi,

this might be a silly question but I'm unfamiliar with DNS so here goes...

should i have any other DNS records other than the two you mentioned above? these are the only ones I have.

You could. If you host a web server you might have
www.YourDomain.co.uk
You might have other specific servers or services as well which could be something like
server2.MyDomain.co.uk
But the two e mentioned earlier are all you need for SBS.

Am i right in thinking that once the DNS is working that i should be able to ping remote.MyDomain.co.uk?

Not necessarily. Only if your router responds to ICMP requests (pings). Most do not as this makes you suceptable to denile of service attacks.
nslookup remote.MyDomain.co.uk
should return your publick IP

ok, i think  somethings gone wrong.

I can ping my server using its address so ICMP must be enabled but i still get "could not find host" on the remote.MyDomain.co.uk address.

I've opened the neccesary ports and checked them via telnet from another machine on a different internet connection.

i've ran the "setup internet address" wizard. i still get a warning at the end about ports not being open but I've googled that and apparently its because UPnP is'nt enabled so SBS cant verify the ports and its OK to ignore the warning.

i've tried changing the DNS of the www address and the change is within 10 minutes, so I dont think the problem is with the DNS not propagating yet?

any suggestions?

If you are getting "could not find host" when pinging the FQDN rather than IP, it is a problem with the configuration with 123-reg.co.uk, not the server itself.
Any chance your internal domain suffix is YourDomain.co.uk and not YourDomain.local?  If so make sure you test from off-site for now.

i've just tried accessing the site from my iphone and it works with remote.mydomain.co.uk!

i've checked in active directory and my internal domain is MyDomain.local, which is correct isnt it?

That being the case, what do you think  the problem could be? i won't ever need to connect in from within the building anyway but is this the way its meant to work?

remote.mydomain.co.uk internally should work but you can have some odd results if the internal domain is ....co.uk which is why I was asking. Where you have .local it should work fine.

When you run the "Connect to the Internet" and "Set Up Your Internet Address" wizards they should automatically create a remote.mydomain.co.uk zone in DNS that will look after this. Assuming you have run those wizards try running the "Fix My Network" wizard. It often works miracles.

Also always a good idea to install and run the Best Practices Analyzer:
