256986 Description of the Microsoft Windows Registry



SUMMARY
The Asynchronous Transfer Mode (ATM) LAN Emulation driver in Windows 2000 supports the use of some special registry parameters for advanced configuration of special ATM LAN Emulation deployments. The use of these parameters is only for knowledgeable network administrators in special testing or production deployment of ATM LAN Emulation.

With these advanced registry parameters, you can use two advanced ATM LAN Emulation configurations:
 * Specify a private ATM address for the LAN Emulation Configuration Server (LECS) instead of the automatic LECS discovery procedures.
 * Specify an ATM address for the LAN Emulation server (LES) instead of a LAN Emulation Configuration server.

This article describes how to edit the registry to specify the ATM address for each type of configuration.



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

How to Specify a Private ATM Address for the LECS
In this configuration, only the LECS that you specify is used by the LEC instance. To specify a private ATM address for the LECS:  Click Start, and then click Run. In the Run box, type regedit, and then click OK. In Registry Editor, click the following key:

 

 Set the UseLecs parameter to 1, or delete this parameter so that it uses a value of 1. Set the DiscoverLecs parameter to 0. Set the LecsAddr parameter to the LECS ATM address that you want.</li> On the File menu, click Exit.</li> Disable, and then enable the ATM adapter to restart the LEC.</li></ol>

How to Specify an ATM Address for the LES
<ol> Click Start, and then click Run.</li> In the Run dialog box, type regedit, and then click OK.</li> In Registry Editor, click the following key:

 

</li> Set the UseLecs parameter to 0.</li> Set the LesAddr parameter to the LES ATM address that you want.</li> Set the LanType and MaxFramSizeCode parameters to appropriate values, if their default values do not match the parameters of the Emulated Local Area Network (ELAN) that is served by the specified LesAddr.</li> On the File menu, click Exit.</li> Disable, and then enable the ATM adapter to restart the LEC.</li></ol>

The following table specifies the effects of different parameter values on an ELAN instance in the ATM LAN Emulation driver for parameters in the following registry key:

 

Note &quot;ATM adapter instance GUID&quot; and &quot;ELAN instance GUID&quot; vary on different computers, but on a computer that has one ATM adapter and is configured to join one ELAN, there is only one instance of an ATM adapter and ELAN.
