LSASS.EXE utilization

Hi guys,

I have a server that seems to be dedicating somewhere between 30% and 60% of its processor time to LSASS.EXE

I've found out a little but not enough about LSASS by googling it and now I'm stuck with a busy processor and no idea where to go next.

Can someone please give me a brief overview of what LSASS actually does, and what sort of things might place demands on it that could use up 30% processor time?

Or, of course, you can suggest a solution if its a common problem? ;-)

its a pretty crucual file stands for local authority security sub system or something like that


Taskmanager is all well and good (start > Run > Taskmgr.exe) but to see what programs have what processes open use....

Well, I had a looksee at Process Explorer and its got lots of nice extra statistics and information about things, but to be honest, it doesn't get the information I'm after, which is "What does LSASS.EXE actually do? And how does it do it?"

I can see from other servers that I can monitor that it is a fairly busy app with hours of CPU time under it's belt, but this one server (Windows 2000 SP4) is suffering from constant high usage of LSASS.

Anyone who knows will be gratefully thanked ;-)

Cheers,

Joe

it handles authentication and ACL access for users and files - it carries all the information from a systems SAM (in standalone mode) or from and SMB interface (in domain mode)
