Lotus Domino Administrator 6.5 Help - Defining a NetBIOS LANA number for a Notes network port

NETWORK CONFIGURATION

Defining a NetBIOS LANA number for a Notes network port
To run NetBIOS on a server, after you complete the Server Setup program, you must determine the NetBIOS LANA number to which the Notes network port will be bound. The NetBIOS LANA number is a logical number that represents a NetBIOS transport protocol stack on a NIC. You must know which transport protocol (NetBEUI, IP, or IPX) Notes workstations and other Domino servers are using for NetBIOS within your workgroup or company.

For example, if the computer has two NetBIOS protocol stacks -- such as NetBIOS over NetBEUI and NetBIOS over IPX -- NetBIOS/NetBEUI uses LANA number 0, and NetBIOS/IPX uses LANA number 1. Depending on how often you configure or reconfigure your system, the LANA numbers may be different than the ones in this example.

If the computer running the Domino server has more than one NIC running the same protocol stack, you must define a different NetBIOS LANA number for each Notes network port for NetBIOS.

NetBIOS systems using the same transport protocol should be in the same Notes named network. If you create Connection documents on the server, the LAN port you select must also be for the same transport protocol.

To define a LANA number in Lotus Domino

1. From the Domino Administrator or Web Administrator, click the server for which you want to define a LANA number.

2. Click the Configuration tab.

3. Do one of these:

From the Domino Administrator's Tools pane, choose Server - Setup Ports.
From the Web Administrator's Port tool, choose Setup.

4. Select the Portname port, where Portname is the name of the NetBIOS port for which you are defining a LANA number.

5. Click "Portname Options," and choose Manual.

6. Enter the correct LANA number.

7. Click OK.

To find the LANA number for a NetBIOS protocol on a Windows NT server

1. Select the Network Control Panel - NetBIOS Interface.

2. Click the Properties button. The NT information appears in the Network Route list.

Windows NT typically has multiple NetBIOS networks configured in the operating system. The most common NetBIOS networks on Windows NT systems are listed below:

Name Protocol

NwlnkNb Novell NetBIOS

Nbf NetBEUI

NetBT NetBIOS over TCP/IP (RFC 1001/1002)

Some protocols can be associated with multiple LANA numbers, one for each network card or dialup network interface. For example, the Network Route entry Nbf->Elnk3 is NetBEUI on a 3Com Etherlink III card, and Nbf->NdisWan5 is NetBEUI on a Microsoft Remote Access Service (RAS) connection.

To find the LANA number for a NetBIOS protocol on a Windows 95/98, XP, or 2000 system

Unlike a Windows NT system, a Windows 95/98, XP, or 2000 system does not have a direct means to see the LANA associations. For Windows 95/98, XP, or 2000 systems you can either review the system's registry bindings or use a Microsoft tool called LANACFG to see and change the LANA number assignments.

The following is an example of the tool's output from a Windows 2000 server. Note that the network route linkages shown are the same as in Windows NT.

lanacfg [options]

showlanapaths - Show bind paths and component descriptions for each exported lana

setlananumber - Change the lana number of a bind path

rewritelanainfo - Verify and write out lana info to the registry

showlanadiag - Show lana diagnostic info

From the DOS prompt, enter

C:\>lanacfg showlanapaths

You see the following:

Lana: 4

-->NetBEUI Protocol-->3Com EtherLink III ISA (3C509/3C509b) in Legacy mode

Lana: 7

-->NetBEUI Protocol-->WAN Miniport (NetBEUI, Dial Out)
