I have a w2k pro machine with Sp1 can't get this to occur, but I don't 
have a printer attached to lpt1, so this could eb why. I did notice that 
doing a dir>prn in a CMD prompt caused the machine to spike to ~70% CPU 
(from essentially 0) with no output for a couple of minutes. The CMD 
never seems to return even though the CPU goes back down to 0

I also noticed that Xitami takes ~1 second to give a 403 to pages like 
/aux or /com1 whereas its in the milliseconds to give the 404 for 
/nothere.htm
