SUMMARY
=======
The following information applies to LAN Manager version 2.1 running under
MS-DOS and OS/2.
One of the features of LAN Manager 2.1 is its ability to automatically save a
user's net connections. When the user logs on again, the connections are
automatically re-established. If the connection requires a password, the user is
prompted.
MORE INFORMATION
================
In LAN Manager versions 2.0c and earlier, users put the net connections that
require passwords in their AUTOEXEC.BAT file, thus eliminating the need to wait
to manually enter the passwords when their system boots up. LAN Manager 2.1
saves these NET USEs in a file called LMUSER.INI, which supersedes any NET USEs
in the AUTOEXEC.BAT file.
The /persistent option of the NET USE command has four parameters:
/persistent:YES
This enables persistent net connections, setting autorestore=yes and
saveconnections=yes in LANMAN.INI. Any connections made after issuing this
command will be saved in LMUSER.INI; any connections deleted will be removed.
/persistent:NO
This turns off persistent net connections altogether. It sets autorestore=no
and saveconnections=no in LANMAN.INI. No connections will be saved or
restored.
/persistent:SAVE
This first writes any existing connections into the LMUSER.INI file. If the
user had any connections in the LMUSER.INI file to servers that are currently
down, they will be dropped. This will set autorestore=yes and
saveconnections=no in LANMAN.INI.
/persistent:FREEZE
This option will set autorestore=yes and saveconnections=no in the LANMAN.INI
file. The difference between this option and the SAVE option is that FREEZE
won't write any existing connections into LMUSER.INI. Also, if the user had
connections in the LMUSER.INI file to servers that are currently down, they
will NOT be dropped.
Disabling Autosave or Customizing Reconnections
-----------------------------------------------
You can either totally disable the autosave feature of LAN Manager 2.1 or
customize the reconnections so you do not have to manually enter any required
passwords.
To disable the persistent connections entirely, use the following command:
net use /persistent:no
This will set autorestore=no and saveconnections=no in LANMAN.INI.
To turn off persistent net connections from within Windows, do the following:
1. From the Control Panel, select the Network icon.
2. From the Networks window Options menu, choose Restore Connections at Log On.
This will toggle (remove the check mark from) the Restore Connections option,
turning off the persistent net connections.
To customize the reconnections to avoid manually entering passwords, do the
following:
1. (Assume that you have no connections.) Add all the connections that can be
made immediately after logon without being prompted for a password (that is,
all connections for which your logon password is the correct one).
2. Type "net use /persistent:freeze". This will freeze the LMUSER.INI file with
the current set of connections so that any subsequent NET USEs do not update
it.
3. In the AUTOEXEC.BAT file, enter the NET USE commands that require passwords.
They will not be automatically added to the LMUSER.INI file.
It is important to note that persistent net connections in LAN Manager 2.1 are
workstation-specific. That is, the LMUSER.INI file is workstation-specific, not
user-specific. System administrators can use the persistent net connection
feature to set up any connections that all users logging on to a specific
workstation would need, and then use the NET USE /PERSISTENT:FREEZE command to
freeze the connections. The system administrator can then configure each user's
individual net connections through the use of logon scripts and batch files.
