Does Code Red infect Windows NT?

One of the recent announcements about Code Red II says that due to a bug the worm only infects Windows 2000. It says the same is true for the original versions of Code Red. If I am following things: Both Windows 2000 and Windows NT are vulnerable to the IIS buffer overflow problem. Only Windows 2000 is infected by the Code Red Worm I and II (so far). Windows NT is not infected by the Code Red Worm I or II. Is this really the case? -Jeff
