    Default LSASS.exe - what is it?

    Hi.
    I've just installed a firewall (nortons) - and when I go on the net - it comes up that LSASS.EXE is trying to reach the net - outbound anyways, it recommends to permit it, and then - a few seconds later - it says something is trying to reach it (inbound) - sometimes it recommends to permit it - but other times it says to block it..

    I haven't ticked the "always use this action" yet - as I'm not to sure waht it is.

    Could some one please let me no if LSASS.exe is a system program - or some trojan?

    THanks

    Process File: lsass or lsass.exe

    Process Name: Local Security Authority Service

    Description: The Windows Local Security Authority Server Process handles Windows Security Mechanisms

    There's also a trojan with a very similar name (I think it was lssass.exe). Discovered that on my Windows 2000 computer last week, because HDD activity was up a fair bit when the computer wasn't being used.

    So it would pay to be wary about allowing applications permission to have outbound or inbound connections. Myself, I never let Microsoft applications access the internet unless it's absolutely essential. I believe General Host Process something-or-rather is safe to block access.

    Here's the information from Answers-that-work:

    ***
    Windows NT4/2000/XP/2003 only. LSASS is the Local Security Authentication Server. It verifies the validity of user logons to your PC/Server (in technical jargon : it generates the process that is responsible for authenticating users for the Winlogon service).

    Recommendation :
    An integral part of the operating system, leave alone.
