Remote operating system guess: Windows XP, Windows 2000, NT4 or 95/98/98SE map run completed — 1 IP address (1 host up) scanned in 3.334 seconds
Using its fingerprinting tests nmap is unable to distinguish between different groups of Microsoft based operating systems – Windows XP, Windows 2000, NT4 or 95/98/98SE. What operating system is the target host running based on the open ports shown above?
