OS/2 TCPBEUI Name Resolution
have the following problem to deal with: An OS/2 system uses NetBIOS over TCP/IP (aka TCPBEUI) and should communicate with a SMB server (likewise using TCPBEUI) on a different subnet. This does not work on OS/2 out of the box without a little bit of help.
This effort was originally driven by non-PC platforms, but soon enough DOS-based (e.g. HP ARPA Services circa 1990, PC/FTP likely earlier) and OS/2-based (MS LAN Manager 2.1 in 1991) implementations of NetBIOS over TCP/IP became available. Instead of requiring a separate IBM TCP/IP product with an add-on NetBIOS kit, a new implementation called TCPBEUI was now part of the Multi-Protocol Network Support (MPTS), alongside the classic NETBEUI. And one more caveat: If the old NBTCP.EXE is not passed the local machine’s IP address correctly, the LAN Requester may fail to start with “duplicate network name” errors.
