- Microsoft Windows NT Workstation version 3.1

SUMMARY
=======

You can get most of the Lan Manager Server and Workstation parameters to appear
in the registry automatically by using the NET CONFIG command.

WARNING: When you run NET CONFIG SERVER (or NET CONFIG SRV), server related
parameters that are normally autoconfigured each time you boot (for example,
maxworkitems)are permanently set in the registry to whatever values Windows NT
is currently using. These parameters will continue to override the defaults
until you change them in the registry. You cannot change the values by running
Control Panel, choosing Server, and then choosing Configure. Consequently, if
you add or remove memory, or change the server size setting
(minimize/balance/maximize), you will not get the benefit of server
autoconfiguration.

MORE INFORMATION
================

By default, the only parameters in the

  HKEY_LOCAL_MACHINE

  \SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

section of the registry are the following:

                        Size  3
                  Lmannounce  0

Windows NT 3.51 and 4.0 have the following additional entries:

                                ==========

                         NullSessionPipes
                        NullSessionShares

However, if you type the following at the command line

  C:\>net config server /HIDDEN:NO
  The command completed successfully.

you will see the following appear in the registry:

  HKEY_LOCAL_MACHINE\SYSTEM

  \CurrentControlSet\Services\LanmanServer\parameters

                        Size  3
                  Lmannounce  0
                     comment  ""
                  srvcomment  ""
                       users  -1
                        disc  15
              autodisconnect  15
                      hidden  1
                    announce  720
                    anndelta  3000
                    userpath  "c:\"
                   sessopens  2048
                     sessvcs  1
                  opensearch  2048
                maxworkitems  128
                maxrawbuflen  65535
                   sessusers  2048
                   sessconns  2048
         maxpagedmemoryusage  -1
      maxnonpagedmemoryusage  -1
            enablesoftcompat  1
          enableforcedlogoff  1
                  timesource  0

Windows NT 3.51 and 4.0 have the same above entries EXCEPT the "disc" and the
"comment" are eliminated.

                     comment
                        disc

This situation also applies to the Lan Manager Workstation section of the
registry. By default the

  HKEY_LOCAL_MACHINE

  \SYSTEM\CurrentControlSet\Services\Lanmanworkstation\parameters

section of the registry is empty. However, if you type

  net config work /CHARTIME:250

the following appears:

  HKEY_LOCAL_MACHINE

  \SYSTEM\CurrentControlSet\Services\Lanmanworkstation\parameters

                    CharWait  3600
          MaxCollectionCount  16
