For channels to work successfully across NetBIOS, the adapter support at each end must be compatible. WebSphere MQ allows you to control the choice of adapter number (lana) by using the AdapterNum value in the NETBIOS stanza of your qm.ini file or the Windows(R) registry and by specifying the -a parameter on the runmqlsr command.
The default LAN adapter number used by WebSphere MQ for NetBIOS connections is 0. Verify the adapter number being used on your system as follows:
On Windows, view the information displayed in the NetBIOS Interface pop-up window. This is accessible by selecting the Network option, which is one of many options displayed when opening the Control icon from the Main Window. Windows can assign multiple 'logical' adapter numbers to one physical LAN adapter. The installation default for 'logical' adapter number 0 is NetBIOS running over a TCP network, not a Token-Ring network. This is not necessary for WebSphere MQ. You should select logical adapter number 1, which is native NetBIOS. WebSphere MQ for Windows uses the 'logical' adapter number for communication.
Specify the correct value in the NETBIOS stanza of the queue manager configuration file, qm.ini, or the Windows registry:
NETBIOS: AdapterNum=n
where n is the correct LAN adapter number for this system.
