LSASS.EXE is the Local Security Authority subsystem, and it is vital to the operation of the system. It handles the low-level details of all Windows 2000 security including logins; therefore you cannot do an END TASK on it and you cannot disable it. As for why it's using 18Mb of RAM--do you have a *lot* of users attached to the server? Is your security setup particularly complicated? LSASS.EXE only takes up 900K on my Win2K Professional system, which is only ever used by me.

interesting...

well, i only have 14 accounts on my system (one is mine, and the rest are various system/domain accounts)... so i am baffled as to why it is 18MB.

i have tried restarting the machine with no change in size.

could it be that i have active directory installed?

then again, this machine is used at home and no one else accesses any of the accounts but me?!?!

thanks...

According to information in the MSDN Library, the directory service under Windows 2000 is actually part of LSASS.EXE--thus, if your machine is a domain controller, it might explain why your LSASS is so much larger than mine. Unfortunately I can't find any work-round for the problem. Out of interest, is having LSASS so big seriously degrading the performance of your machine, or are you just optimising for the sake of optimisation?

i don't believe it is degrading the performance... since i still have about 100MB RAM available... just curious as to why it is like this...

thanks!
