NWCONFIG-X-433: Warning: You do not have a shared LAN driver loaded. You need to choose the proper shared driver for OS/2 to see the network.
Source: NWCONFIG.NLM
Explanation: If you are sharing a network board between the server and the client, you will need to load both a real and a sharing LAN driver. The real LAN driver allows the server to see the network, and the shared LAN driver allows the client to see the network.
Action: Load the correct sharing LAN driver. There is a line in the CONFIG.SYS file that loads the corresponding sharing driver on the client (TOKENSHR, TOKENLNK, or LANSHARE).
