<NT prior to 3.x was called MS LAN Manager, and didn't compare particularl <well to anything. NT prior to NT wasn't. NT was a divergent design that is non dos filesystem. LANMAN is the networking component of WFW3.11. The divergence from OS/2 and windows3.x was also influenced by MS getting Cutler an OS heavy that created DEC RSX-11 and early VMS incantations. the idea of NT was clean sheet 32bit OS with multitasking, multiprocessing and inherant networking all of which were glueons for windows. OS/2 was a different path from NT with a different base designer. In reality NT is not a stand alone OS as it requires windows as the user interface wher OS/2 it was a add on. Also the roots for OS/2 go back further and it was the DOS replacement with all the things that DOS still does not have. Allison
