Open nmap or zenmap and do quick scan plus

Thanks dude.

nmap is not a reliable way to determine OS, use p0f as OTW suggested

But the picture you posted worked perfectly...
Xprobe gives you probability of other os too..
But by the results its most probably mac osx 10

No, it's OS is Windows. I was testing it.

Xprobe hasn't been updated in awhile. Try using p0f.
