Hi, if you have a MAC address, how can you find ou tit's ip address? Thanks in advance Sebastiaan -- NT is the OS of the future. The main engine is the 16-bit Subsystem (also called MS-DOS Subsystem). Above that, there is the windoze 95/98 16-bit Subsystem. Anyone can see that 16+16=32, so windoze NT is a *real* 32-bit system.
