Method 1: Use Registry Editor Domain controller locator configuration for Windows XP Professional Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows On a Windows-based computer, an Active Directory domain member requires additional configuration to support single-label DNS names for domains. Specifically, the domain controller locator on the Active Directory domain member does not use the DNS server service to locate domain controllers in a domain that has a single-label DNS name unless that Active Directory domain member is joined to a forest that contains at least one domain that has a single-label DNS name. Without modification, an Active Directory domain member in a forest that does not contain any domains that have single-label DNS names does not use the DNS Server service to locate domain controllers in domains that have single-label DNS names that are in other forests. Client access to the domains that have single-label DNS names fails if NetBIOS name resolution is not correctly configured. To enable an Active Directory domain member to use DNS to locate domain controllers in domains that have single-label DNS names that are in other forests, follow these steps: Click Start, click Run, type regedit, and then click OK. Locate and then click the following subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters In the right pane, locate the AllowSingleLabelDnsDomain entry. If the AllowSingleLabelDnsDomain entry does not exist, follow these steps: On the Edit menu, point to New, and then click DWORD Value. Type AllowSingleLabelDnsDomain as the entry name, and then press ENTER. Double-click the AllowSingleLabelDnsDomain entry. In the Value data box, type 1, and then click OK Quit Registry Editor.

If an Active Directory forest root has a single-label DNS name, all domain controllers in that forest typically must dynamically register DNS records in a single-label DNS zone that matches the DNS name of the forest root. By default, Windows-based DNS client computers do not attempt dynamic updates of the root zone "." or of single-label DNS zones. To enable Windows-based DNS client computers to try dynamic updates of a single-label DNS zone, follow these steps: Click Start, click Run, type regedit, and then click OK. Locate and then click the following subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DnsCache\Parameters In the right pane, locate the UpdateTopLevelDomainZones entry. If the UpdateTopLevelDomainZones entry does not exist, follow these steps: On the Edit menu, point to New, and then click DWORD Value. Type UpdateTopLevelDomainZones as the entry name, and then press ENTER. Double-click the UpdateTopLevelDomainZones entry. In the Value data box, type 1, and then click OK Quit Registry Editor
