lsass.exe consumes too much cpu

By R. A. Caluste ·
i have a remote server running RRAS (to vpn to main server), active directory (child) and dns. It has two network interfaces, one to the private intranet, one with public address.

after a day of activity, lsass.exe shows in the task manager/processes consuming 99 in the cpu field.

is this indicative of an attack? i disabled both the network interfaces and after a few minutes, i got the cpu cycle back to the System Idle process.

any suggestions?

this happens alot. thanks.

If you have Anti-virus (Mcafee) and Exchange running on this system, this is the cause.

LSASS.EXE is the local security authority, and it could be using lots of CPU resources because it's processing a lot of logon requests--say, if a hacker were trying to brute-force one of your passwords.

On another thought, what SP are you at? There were some memory leak issues with it once.
