When you attempt to load the contents of an Lmhosts file into the NetBIOS Remote Cache Name Table using the Nbtstat -R command, you may notice that the entries are not loading. You can view this by using the Nbtstat -c command.


The Lmhosts file is very specific in its required syntax and may be incorrectly formatted.


To troubleshoot this issue, use the following:

  • Open the Lmhosts file in a text editor, such as Notepad.exe or, and place three or four carriage returns at the bottom of the file.

    NOTE: If you are using Notepad.exe, then make certain that you do not save the file using Unicode.
  • Make sure the Lmhosts lookup is enabled by performing the following steps:

    1. Click Start, point to Settings, and click Control Panel.
    2. Double-click Networks, on the Protocols tab, and double-click TCP/IP Protocol.
    3. On the WINS Address tab and click the Enable LMHOSTS Lookup to enable it.

      NOTE: You need to restart your computer for this change to take effect.
  • Verify that your Lmhosts file is in the proper folder and has no file extension. For more information, see the following article in the Microsoft Knowledge base:
