I've been using Mark Russinovich's NTCrash2.exe utility for quite a while now, and I must say that it is an excellent piece of kernel stress-test software.

So far, I've discovered that every Symantec/Norton service (that I've tested thus far) will crash when using NTCrash2. Daemon Tools 3.47 crashes as well. Fortunately, Daemon Tools 4.0 is immune, and avast! antivirus is also immune.
