Can anyone tell me what this is and what it does.

LSASS.EXE is the Local Security Authentication Subsystem Server.

Basicly when anything (including you, and services) log on locally it goes through LSASS.

If you are having problems like this service running with high processor usage all the time or lots of memory, you need to update to the latest service pack of windows and exchange (if on the machine).

Thank you for your help. I was surprised I couldn't find any help from within windows help and it wasn't referenced in Mark Minasi book either.
