CHECK LIST: VERYFYING DNS BEFORE INSTALLING ACTIVE DIRECTORY

STEP 1

Verify that a network connection on the server on which you are installing Active Directory is configured with a DNS server to query for domain names. If you are installing Active Directory on a server in an existing forest, then the network connection of the server must be configured with one or more DNS servers. If not, then configure the network connection with the IP addresses of one or more DNS servers. If you are installing Active Directory to create a new forest, and no DNS servers are available on the network, then the Active Directory Installation Wizard can automatically install and configure a local DNS server. The DNS server will be installed on the server where you are running the wizard and the server's preferred DNS server setting will be configured to use the new local DNS server. If you install a local DNS server using the Active Directory Installation Wizard, you may stop using this checklist.

STEP 2

Verify DNS resource records.

If you are installing Active Directory on a server in an existing forest, verify that the appropriate service (SRV) resource records and the corresponding address (A) resource records exist in DNS.

-> Additional domain controller in an existing domain: _ldap._tcp.dc._mcdcs.ActiveDirectoryDomainDNSName

-> First domain controller in a new child domain: _ldap._tcp.dc._mcdcs.ParentActiveDirectoryDomainDNSName

-> First domain controller in a new tree: _ldap._tcp.dc._mcdcs.ForestRootDomainDNSName

If the required SRV and A resource records do not exist in DNS, you can add these records
