MORE INFORMATION
================

You may want to have a secondary DNS server to provide redundancy throughout
your network for host name resolution. A secondary DNS server will keep a copy
of the zone files for name resolution, but any changes to these files will need
to be made on the primary DNS server.

NOTE: These changes can be made remotely by using DNS Manager.

The steps below assume that you have already installed Microsoft DNS Server on
the intended secondary server.

1. Click the Start button, point to Programs, point to Administrative Tools, and
   then click DNS Manager.

2. From the DNS menu, click New Server.

3. Type the IP address of your secondary DNS server in the Add DNS Server dialog
   box, and then click OK.

4. Repeat steps 2 and 3 using the IP address of your primary DNS server.

   NOTE: If added successfully, it will expand and you should see the primary
   zone(s) that exist on that server.

5. Right-click the secondary DNS server and click New Zone.

6. Click Secondary, type the zone name in the Zone field, and type the IP
   address of the primary DNS server in the Server field.

   NOTE: You can also simply drag the hand icon to the zone beneath the primary
   DNS server, and DNS Manager will automatically fill in this information for
   you.

7. Click Next, type the zone name in the Zone name field, type the zone file
   name in the Zone File field, and click Next.

   NOTE: If you used the hand icon in step 6, this dialog will be automatically
   entered. Click Next.

8. Type the IP address of the primary DNS server, click Add, and then click
   Next.

   NOTE: If you used the hand icon in step 6, the IP master will be automatically
   entered. Click Next.

9. Repeat steps 5 through 8 for the reverse zone.

If all of the above is correct, you should receive one or more of the following
event messages in Event Viewer on the primary DNS server:

   Event ID   : 731
   Source     : DNS
   Description: DNS Server transfer of zone <zone-name> to DNS server at
                <ip-address>, successfully completed.

-or-

   Event ID   : 850
   Source     : DNS
   Description: DNS Server transfer of zone <zone-name> to DNS server at
                <ip-address>, successfully completed.

-or-

   Event ID   : 6001
   Source     : DNS
   Description: DNS Server transfer of zone <zone-name> to DNS server at
                <ip-address>, successfully completed.

On the secondary DNS server, you should receive one or more of the following
event messages in Event Viewer:

   Event ID   : 702
   Source     : DNS
   Description: New Version <zone file version number> of zone <domain
                name> found at DNS Server at <ip-address>. Zone transfer is
                in progress.

-or-

   Event ID   : 3150
   Source     : DNS
   Description: DNS Server wrote new version of zone <zone-name> to file
                <zone-name>.dns. The data is the new version number.

-or-

   Event ID   : 6522
   Source     : DNS
   Description: New Version <zone file version number> of zone <zone-name>
                found at DNS Server at <ip-address>. Zone transfer is in
                progress.
