Yes, to the best of my knowledge, you are right. NT/2000/XP may parse 
AutoExec.bat for environment variables and path entries, however. See

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q100843
http://www.windows2000faq.com/Articles/Index.cfm?ArticleID=14948

for how this works, and

http://www.windows2000faq.com/Articles/Index.cfm?ArticleID=14823

on how to control AutoExec.bat parsing

There are other viruses like W32/Vote which do the same (among 
others). It is certainly something to watch out for, considering a 
lot of people using NT 4 at work tend to "sneaker-net" files back and 
forth between work and home machines, most of which tend to be non-NT 
Windows flavors who would be hit hard.
