I have NIS 2010 running on two computers: one with Windows XP SP3 and the other is a new one with Windows 7 Home Premium 64-bit. When I run the Shields Up test from Gibson Research (http://www.grc.com/intro.htm) on my old computer the test shows “stealth” status on all ports tested. When I run the test on the new computer I get “stealth” mode on most ports but “closed” on some ports, meaning the closed ports are responding to the test that there is a port there but it is closed to connections. While that is somewhat comforting, shouldn’t NIS 2010 be doing something to make all ports “stealth”? Is there some sort of configuring I need to be doing here?
