DNS for Dummies

How do you set up and verify a DNS is working properly on an Small Business Server 2008? I would like to use the Active Directory Secure replication for syncing the servers.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

To verify replication between servers, check sequence numbers on zones, must be equal on all servers.

The only thing I've needed to do with DNS on an SBS2008 is set up forwarders to my ISPs DNS servers. Other than that, every thing is done for you - forward and reverse lookup zones are set up, DHCP requests are registered with DNS etc.

You can check if DNS is operating by going to a PC in the domain and do a nslookup from the command prompt -

C:\Users\loginname>nslookup
Default Server:  servername.domain.tld
Address:  "IP Address of server"

To check Internet lookup -
www.google.co.uk
Server:  servername.domain.tld
Address:  "IP Address of server"

Non-authoritative answer:
Name:    www.l.google.com
Addresses:  209.85.229.104
          209.85.229.103
          209.85.229.99
          209.85.229.147
          209.85.229.105
Aliases:  www.google.co.uk
          www.google.com

To check servername is resolving -
> "SERVERNAME"
Server:  servername.domain.tld
Address:  "IP Address of server"

Name:    servername.domain.tld
Address:  "IP Address of server"

To check PC names are resolving
> "name of a domain PC"
Server:  servername.domain.tld
Address:  "IP Address of server"

Name:    "FQN of PC"
Address:  "IP Addrress of PC"
>quit

To check reverse DNS lookup
C:\Users\loginname>tracert "Ip Address of PC"
Tracing route to "name of PC".domainname.tld ["IP Address of PC"]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  "FQN of PC" ["IP Address of PC"]

Trace complete.

Just doing the above indicates the server DNS is running and resolving PC names, does reverse lookup and can resolve Internet names. Of course, if you're not using the server's DHCP and DNS then the above won't resolve correctly.
