You have initiated an active operating system fingerprinting attempt with nmap against a target system:

[root@ceh NG]# /usr/local/bin/nmap -sT -O 10.0.0.1

Starting nmap 3.28 ( www.insecure.org/nmap/) at 2003-06-18 19:14 IDT

Interesting ports on 10.0.0.1:

(The 1628 ports scanned but not shown below are in state: closed)

Port State Service

21/tcp filtered ftp

22/tcp filtered ssh

25/tcp open smtp

80/tcp open http

135/tcp open loc-srv

139/tcp open netbios-ssn

389/tcp open LDAP

443/tcp open https

465/tcp open smtps

1029/tcp open ms-lsa

1433/tcp open ms-sql-s

2301/tcp open compaqdiag

5555/tcp open freeciv

5800/tcp open vnc-http

5900/tcp open vnc

6000/tcp filtered X11

Remote operating system guess: Windows XP, Windows 2000, NT4 or 95/98/98SE Nmap 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.
