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.


By default, the only parameters in the



section of the registry are the following:

                         Size  3
                   Lmannounce  0

Windows NT 3.51 and 4.0 have the following additional entries:



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:



                         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.


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



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

net config work /CHARTIME:250

the following appears:



                     CharWait  3600
           MaxCollectionCount  16
               CollectionTime  250
                     KeepConn  600
                      MaxCmds  50
                  SessTimeout  45
                   SizCharBuf  512
                   MaxThreads  17
                    LockQuota  6144

               UseCloseBehind  1
                BufNamedPipes  1
            UseLockReadUnlock  1
             UtilizeNtCaching  1
                   UseRawRead  1

             BufReadOnlyFiles  1
          ForceCoreCreateMode  1
        Use512ByteMaxTransfer  0

Windows NT 3.51 and 4.0 have the same above entries.
