Determining LANA Numbers in Windows 95 (158781)

SUMMARY

To determine which LANA numbers are being used on a Windows 95 client, type net diag /status at a command prompt.

The resulting prompt asks you to enter the remote computer's NetBIOS name, or to press ENTER to examine a local adapter's status. It then prompts you to select the LANA number you want to use.

NOTE: You are prompted for a LANA number to use only if you are using more than one protocol.

MORE INFORMATION

A NetBIOS-providing protocol set to be the default protocol is set to LANA 0. To find out which protocol is on which LANA, check the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans
Beneath this key is a series of \000x branches corresponding to the network protocols installed. Skipping the NetBIOS-providing protocol set as the default protocol, find the NetBIOS protocols being used and number their LANA numbers backwards from seven.

Examples

A Windows 95-based computer is using NetBIOS over IPX, TCP/IP, and NetBEUI. All three are NetBIOS providers. NetBEUI has been set as the default protocol. The NET DIAG /STATUS command shows:

Please enter remote computer's NetBIOS name, or press ENTER to examine a local adapter's status.

Please enter the LANA number you wish to use. Choose from the following NetBIOS-providing LANA(s): 0 6 7

The registry shows:

HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \Class \NetTrans \0000 - IPX/SPX \0001 - NetBEUI \0002 - TCP/IP \0003 - NetBIOS over IPX Using the above guidelines, you can determine that:

NetBEUI is on LANA 0 (default protocol)
NetBIOS over TCP/IP is on LANA 7
NetBIOS over IPX is on LANA 6

Note that IPX/SPX is skipped because it is not a NetBIOS-providing protocol. Had NetBEUI not been set to be the default protocol, the NET DIAG /STATUS command would not have listed LANA 0:

Please enter the LANA number you wish to use. Choose from the following NetBIOS-providing LANA(s): 6 7

In this case, LANA numbers 6 and 7 are being used, and no NetBIOS- providing protocol has been set as the default protocol. Otherwise, the display would show LANA 0 being used.
