Determining LANA Numbers in Windows 95

The information in this article applies to:
  • Microsoft Windows 95

SUMMARY

To determine which LANA numbers are being used on a Windows 95 client, type "net diag /status" (without quotation marks) 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 asks you to select the LANA number you want to use.

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.
