why the lsass exe keeping reading data my harddrive

I installed Win Vista Beta2, and because I have 1.5G physical memory I turn the virtual memory to 0MB. But when I use Win vista, the light of harddrive keeping flashing, so I open task manager to see which task is reading or writing. I find it's lsass.exe. Then I run "tasklist /svc" in cmd model, it tell me lsass.exe means samSs service. so I want to stop the samSs service, but windows tell me it's about Security Center, I can't stop it.
Now the question is, how can I stop the keeping reading and writing? It makes my harddrive so hot even when I don't run any other programs.

Are you sure that it's lsass? Just because it's using the CPU doesn't mean that it's doing anything with the hard drive, and I don't know of any program that can actually tell you what is reading or writing to a drive. Is there anything in taskmanager about defrag or defragntfs? That is likely what is doing stuff as it automatically attempts to defrag the hard drive when it sees that it is needed. ---------- Mark Dietz PROnetworks <http://www.pro-networks.org>
