## SYMPTOMS

A build of the Addname utility that was initially released with Windows for Workgroups version 3.11 causes problems when used. The "addname /save" command generates strange characters in the LMhosts file.
When you start the machine with a correct Lmhosts file, the machine boots and the Lmhosts entries get loaded properly. But "addname /save" (which saves the Lmhosts cache entries to the Lmhosts file) corrupts the Lmhosts file with strange characters. In the example below, the characters on the left are IP addresses; the characters on the right are meaningless:

    137.61.97.229       "39FC10x1B\0xFFB\ 1\0xFF"     #DOM:
    57.51.50.65         "          Qa=\0xFFA6"     #PRE
    32.32.52.48         "      \0xFF\0x01;\0xFF \0x1B\0xFFB\0x00\0x00"
    58.67.66.0
    RO\0xFF\0xFF\0xFF\0xFF\0xFF\0x0A\0xFFQ\0xFF*\0xFF!\0xFF\0xFF

## CAUSE

One of the Addname builds initially released with the WFWG 3.11 TCP/IP stack (1.0a) was corrupt, causing problems.

## RESOLUTION

For a workaround, use the Addname utility that comes with either LAN Manager 2.2 TCPstack or WFWG 3.1 TCP connections pack.
To resolve the problem, obtain the updated Addname build from the Internet.

## MORE INFORMATION

The Addname utility shipped with every Microsoft TCP/IP stack. You use it to add a NetBIOS name and its IP address to the cache used for remote NetBIOS name resolution in TCP/IP-based networks.

### Format of Addname command

- addname computername ipaddress
- addname computername /delete
- addname /load (to load an LMhosts file to cache)
- addname /save (to save the cache contents to a file--usually LMhosts).
