Or poor password policies...

Most pubstros I've seen succeed do so with just password guessing (and 
relatively trivial guessing at that) -- not that they don't have other 
methods, just that pwd guessing gets them plenty of victims.  Are these 
machines visible to the world for any kind of standard NT 
authentication connections?  If so, start with the simplest (and 
probably most likely), which is user slackness (blank, "admin", 
"guest", "pass", "aaaaa", "qwerty", "12345", etc passwords).

Vulns common to NT and 2K but not XP would be fairly rare (other than 
in non-XPSP2 IE 6??), unless you have very limited patch control over 
non-XP machines but good control of XP patching.
