NWCONFIG-X-432: Warning: For NetWare for OS/2, you need at least one LAN driver and also a shared LAN driver (TOKENSHR, etc). You need the LAN driver to complete the installation, and the shared driver to see the network from OS/2.
Source: NWCONFIG.NLM
Explanation: If you are sharing a network board between the server and the client, you will need to load at least two LAN drivers. One LAN driver will be a sharing driver which will allow the client to have access to the network. The other LAN driver will be the driver for the installed network board. You might have multiple real LAN drivers, one for each network board, but only one sharing driver.
Action: If you are sharing a network board with the client, load the preselected sharing driver (TOKENSHR, TOKENLNK, or LANSHARE) and the LAN drivers corresponding to the installed network boards. If you are not sharing a network board, load only the LAN drivers corresponding to the installed network boards.
