SYMPTOMS
When you use a Microsoft Windows 2000 Server-based or Microsoft Windows Server 2003-based domain controller, some services of the Active Directory directory service, such as Lightweight Directory Access Protocol (LDAP) services, may not function correctly. When you try to troubleshoot the domain controller, you may also experience the following symptoms:  When you examine the Netlogon.dns file, you see text entries that display only the host name of the domain controller and not the fully qualified domain name (FQDN). When you run the Dcdiag.exe command-line tool at the command prompt, the output indicates that the FQDN of the domain controller could not be resolved. When you use the DNS snap-in to examine the DNS record in the _msdcs DNS zone, the FQDN of the domain controller appears as, where   is the name of the Windows DNS server. When you restart the domain controller, the Windows Server 2003 operating system recognizes the domain controller as a host that does not have a domain name. For example, if the FQDN of the domain controller is host.domain.com, the operating system recognizes only the host name (&quot;host&quot;) and not the domain name (&quot;domain.com&quot;).  When the DNS service is started, the following event is recorded in the DNS server event log:

Event ID: 414

Type: Warning

Date:

Time:

Source: DNS

User: N/A

Computer:

Description:

The DNS server machine currently has no DNS domain name. Its DNS name is a single label hostname with no domain (example: &quot;host&quot; rather than &quot;host.microsoft.com&quot;). You might have forgotten to configure a primary DNS domain for the server computer.

For more information, see either &quot;DNS server log reference&quot; or &quot;To configure the primary DNS suffix for a client computer&quot; in the online Help. While the DNS server has only a single label name, all zones created will have default records (SOA and NS) created using only this single label name for the server's hostname. This can lead to incorrect and failed referrals when clients and other DNS servers use these records to locate this server by name.

To correct this problem:

1) Open ControlPanel.

2) Open System applet.

3) Select NetworkIdentification tab.

4) Click the &quot;Properties&quot; button and enter a domain name or workgroup name; this name will be used as your DNS domain name.

5) Reboot to initialize with new domain name.

After reboot, the DNS server will attempt to fix up default records, substituting new DNS name of this server, for old single label name. However, you should review to make sure zone's SOA and NS records now properly use correct domain name of this server.  When you try to restart the Exchange System Attendant service on a computer that is running Microsoft Exchange 2000 Server, the service does not start.</ul>

CAUSE
This issue may occur because of a corrupted registry entry in the following registry subkey:

One of more of the following registry entries in this registry subkey may be corrupted:
 * Domain
 * Hostname
 * NV Domain
 * NV Hostname

If Active Directory Service Location (SRV) resource records refer to the incorrect domain name, the domain controller cannot resolve the domain name. Because of this, Active Directory services may not work correctly.

RESOLUTION
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, use Registry Editor to remove and re-create the registry entries that are mentioned in the &quot;Cause&quot; section. To do this, follow these steps: <ol> Click Start, click Run, type regedit in the Open box, and then click OK.</li> In Registry Editor, locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

</li> In the right pane, right-click Domain, and then click Delete.</li> When you are prompted to confirm the deletion, click Yes.</li> Repeat steps 3 and 4 for the Hostname, NV Domain, and NV Hostname registry entries.</li> On the Edit menu, point to New, and then click String Value.</li> Type Domain, and then double-click Domain.</li> In the Value data box, type the Active Directory domain name, and then click OK. For example, you may type contoso.com as the domain name.</li> Repeat steps 6 through 8 for the NV Domain registry entry.</li> On the Edit menu, point to New, and then click String Value.</li> Type Hostname, and then double-click Hostname.</li> In the Value data box, type the computer name, and then click OK.</li> Repeat steps 10 through 12 for the NV Hostname registry value.</li> Quit Registry Editor.</li> Click Start, click Run, type services.msc in the Open box, and then click OK.</li> In the right pane of the Services window, locate and then click Net Logon.</li> <li>On the Action menu, click Stop.</li> <li>On the Action menu, click Start.</li></ol>
