I desperately need help using NmapWIN with winXp. I try to scan my friend (no im not doing it with evil intentions) to determine his OS, you know, to see if it works. NmapWIN always brings it back, stating his comp is not responding to the pings. Not true! I ping him with MS-DOS and it replies! Is there an internal setting I need to set it on? I want to use NmapWIN!
