Windows NT 4.0 Server Upgrade Guide 141
Next, Windows Server 2003 indicates that it needs to communicate with DNS to set up the
records needed for Active Directory to function properly. This Windows NT 4.0 domain controller
may be the first Windows Server 2003 server in the domain, so there is a good chance that no
DNS servers exist at this stage of the upgrade. The figure below shows the diagnostic results that
state the problem.
Figure 66. DNS Warning dialog box
In this example, this computer is the first to be upgraded to Windows Server 2003. There are no
other DNS servers available in the domain. The option to Install and configure the DNS server
on this computer was chosen. This option also makes sure the TCP/IP settings are changed to
point to itself as the primary DNS server. Although not necessary, it is a good idea to allow a DNS
server to create and handle all the necessary Active Directory records.
In order for Active Directory to start up and function properly after the upgrade, a DNS server must
be present. The DNS server used must support SRV records and dynamic updates among other
things to allow Active Directory to work properly. Careful inspection of DNS should follow the
Active Directory setup to check for the necessary DNS entries.
After answering this question, the wizard prompts for the default permissions to be used for user
and group objects as the following figure shows.
