How to Display Network Registry Parameters

ID: Q102469

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1
Microsoft Windows NT Server versions 3.51, 4.0
Microsoft Windows NT Workstation versions 3.51, 4.0

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

                       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 [ASCII 147]disc[ASCII 148] and the [ASCII 147]comment[ASCII 148] 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

Windows NT 3.51 and 4.0 have the same above entries.
