SYMPTOMS
When you try to add a Windows NT 4.0 Workstation-based computer to a domain, you may not be able to add the computer and you may receive the following error message:

Domain controller for this domain could not be found

Event Viewer may record event ID 5719 in the System event log:

No Windows NT Domain Controller is available for domain (domain_name).

The following error occurred: There are currently no logon servers available to service the logon request.



CAUSE
This behavior can occur if a Lmhosts file is in use, and the Lmhosts file contains an incorrect entry that is preloaded into the network basic input/output system (NetBIOS) name cache by using the #PRE extension.



RESOLUTION
If you do not need to use the Lmhosts file, disable the file:
 * 1) Click Start, point to Settings, click Control Panel, and then double-click Network.
 * 2) Click Protocols, click TCP/IP Protocol, and then click Properties.
 * 3) Click WINS Address.
 * 4) Click to clear the Enable LMHOSTS Lookup check box.
 * 5) Click OK, and then click Close.
 * 6) Restart your computer when you are prompted to do so.

If your network configuration requires that you use a Lmhosts file for NetBIOS name resolution, verify that all static mappings in the Lmhosts file are correct.

NOTE: The Lmhosts.sam file is located in the %SystemRoot%\System32\Drivers\Etc folder.
