I ran into an interesting (weird?) behaviour of os detection of nmap v5.00: Sometimes (not always) I get inaccurate results when I scan from a linux box while doing the same scan from a Windows XP box the os detection is perfect. E.G. scanning a Windows 2003 Server SP2 (nmap -O -sSU -T4 <target>): Linux: No exact OS matches Windows: OS Details: Microsoft Windows Server 2003 SP1 or SP2
This could be caused by different network conditions between the two scanning machines and the target. Are they all on the same network? Does the Linux scan print out a fingerprint? If so, then it probably had a very close, but not exact, match. Try adding the --osscan-guess option to force it to be printed.
