What should you do?

You are the systems administrator for your company. The network consists of a single Active Directory domain. You are migrating from Windows Small Business Server 2003 to Windows Essential Business Server (EBS) 2008.

The network contains a Domain Name System (DNS) server named DNS1 that contains a standard primary zone for the domain. You migrate the DNS settings from DNS1 to the Windows EBS servers. You want to ensure that the DNS zones are configured correctly on the Windows EBS servers.

A.
Ensure that the forward and reverse lookup zones are integrated with Active Directory on the Management Server.

B.
Ensure that the forward and reverse lookup zones are integrated with Active Directory on the Messaging Server.

C.
Ensure that the forward and reverse lookup zones are integrated with Active Directory on the Security Server.

D.
Ensure that the forward and reverse lookup zones are configured as primary zones on the Management Server.

E.
Ensure that the forward and reverse lookup zones are configured as primary zones on the Messaging Server.

F.
Ensure that the forward and reverse lookup zones are configured as primary zones on the Security Server.

Explanation:
You should ensure that the forward and reverse lookup zones are integrated with Active Directory on the Management Server and the Messaging Server. When you install Windows EBS 2008, you can configure Windows EBS to join a new or an existing Active Directory domain. When you configure Windows EBS to join a new domain, the DNS Server service is installed on the Management Server and the Messaging Server. Both these servers are configured as primary servers for the new domain with an Active Directory-integrated zone. When you configure Windows EBS to join an existing domain, the Installation Wizard detects if the DNS zone for the specified domain is an Active Directory-integrated zone or a stand-alone zone. If the DNS zone is not integrated with Active Directory, the DNS Server service is not installed on the Management Server and the Messaging Server.

In this case, you should manually prepare the DNS Server services for migration. To do this, you should perform the following steps:
1. Log on to the existing DNS server by using a domain administrator account if the server is joined to the domain. If the DNS server is not joined to the domain, log on to the server as local administrator.
2. Open the DNS snap-in by going to Start > Administrative Tools > DNS.
3. In the left pane, expand the Forward Lookup Zones node, right-click the domain to which you joined Windows EBS, and then click the Properties option.
4. Click the Start of Authority (SOA) tab and verify that the value in the Primary server field matches the fully qualified domain name (FQDN) of the primary DNS server that you are using now.
5. If you see a different server name in this field, the DNS server you are using is not the primary DNS server for this zone. You must perform these steps on the primary DNS server, which is the server specified in this field.
6. Click the Zone Transfers tab, and verify that the Allow zone transfers check box and the Only to servers listed on the Name Servers tab option is selected.
7. Click the Name Servers tab, and then click the Add button.
8. In the Server fully qualified domain name field in the New resource record dialog box, type the FQDN of the Management Server. Then click the Resolve button.
9. Click the OK button to close the Properties dialog box.

When you migrate DNS settings from a DNS server that is not integrated with Active Directory, you should do the following on the Management Server and the Messaging Server to ensure that the DNS settings are correct:

* Ensure that both forward and reverse lookup zones are migrated correctly.
* Ensure that both forward and reverse lookup zones are integrated with Active Directory as primary zones.
* Remove legacy name servers from the forward and reverse lookup zones.
* Add a CNAME record for Web Proxy Automatic Discovery (WPAD).
* Remove any forwarders, and confirm the presence of root hints.

You should not ensure that the forward and reverse lookup zones are integrated with Active Directory on the Security Server. During the installation of Windows EBS, the DNS Server services are installed only on the Management Server and the Messaging Server. Therefore, you should check the Management Server and the Messaging Server.

You should not ensure that the forward and reverse lookup zones are configured as primary zones on the Management Server, Messaging Server, or Security Server. Windows EBS requires Active Directory-integrated zones to function correctly. Also, these zones are configured only on the Management Server and the Messaging Server, and not on the Security Server.
