Title: Preserving the 3+Open Name Service's NS_DOM Files
date: 08/24/90

Copyright 3Com Corporation, 1991.  All rights reserved.

The 3+Open Name service uses database files to keep track of all the names
that are used on the network.  These files are called NS_DOM (Name Service
Domain) files.  For each domain in the name service, there is one NS_DOM.xxx
file, each with its own extension, on the name server.  The extensions are
numbered sequentially, so a name server with eleven domains has NS_DOM files
from 000 to 010.

If the NS_DOM files become corrupted, it is difficult to repair them; usually,
they must be recreated manually by adding all the names back in--a very
time-consuming process.

However, if there is a copy of all the NS_DOM files stored off the name
server, they can be copied back to the server.  The following procedure
explains how to copy and store the database files elsewhere in case the
original files get corrupted.

1.  From an admin station, type:  NET ADMIN \\servername /C

2.  From the server prompt, type:  NET STOP 3NAME

3.  Break out of the server prompt by pressing Ctrl-C after 3NAME
has successfully stopped.

4.  NET USE to the server's C$ sharename and change directory to
C:\3Open\3Name.

5.  Copy the NS_DOM.* files to a diskette or to a local hard disk.

6.  Type:  NET ADMIN \\servername /C

7.  From the server prompt, type:  NET START 3NAME

3Com also recommends that you make frequent server backups so there is a
complete copy of server files on tape.
