Hi,
I've upgraded my domain from nt 4.0 to win2003 Server, all has gone more or less to plan, I have DNS installed on one permanent 2003 server at present and have installed ad on a second 2003 server, my question is, should I install DNS on this server also as a backup or is this inviting trouble?  Thanks

Hi,

Having a redundant DNS service is considered a best practice.

Install DNS service on both servers, make your DNS zone (s) Active Directory integrated, you won't have to worry about replication. That should yield no trouble at all.

If you have special constraints, keep up with the classic "primary - secondary" scheme, won't be a problem either.

I would install the DNs service on your second server...  I would then point all of your clients and server to use BOTH DNS servers (in case one fails, the clients will automatically start using the second one).

If you have configured forwarding on your first DNS server, you will have to configure forwarding on your second one too.  (In the DNS console, right click your DNS server and choose properties from the drop down box.  Then click the forwarding tab and enter the IP address of your local router or of your ISP DNS server here)

Also, I would enable this second machine as a Global Catalog server :  http://support.microsoft.com/?kbid=313994

Also, if you use Windows DCHP, you might want to make this server also a DHCP server for redundancy... but make sure that you don't overlap your scopes...  

Also, if you use Wins, you may want to make this server a WINS server as well...for redundancy...

Also, you can install printers on this server too...for redundancy...just make sure that the clients have mappings to both...
