Further estranging itself from Microsoft Corp’s LAN Manager, IBM Corp has extended its February agreement with Novell Inc to cover Portable NetWare for the AIX Version 3 on the RS/6000. The facility will mean that users can integrate the RS/6000 into existing NetWare networks, enabling MS-DOS, OS/2, Windows and Apple Computer Inc Macintosh NetWare clients to access AIX applications, enhancing interoperability and sharing of data. Despite the rift with Microsoft, IBM says that it is evaluating developing its LAN Server version of LAN Manager for AIX Version 3 for the RS/6000.
