To troubleshoot any of these files on a local computer, do the following:
Make sure the format of entries in each file matches the format defined in the sample file originally provided with TCP/IP.
Check for spelling errors.
Check for invalid IP addresses and identifiers.
Note
- By default, the Lmhosts file does not exist. There is an Lmhosts.sam sample file that you can use as a basis for creating an Lmhosts file.
