Hello,

I have a Windows 2000 SP4 DC.
I don't know why, but from time to time the CPU is near to 100% for
lsass.exe.

I found several articles for Windows 2000 SP1 or SP2.

But what causes this high CPU usages of lsass in Windows 2000 SP4?

Any ideas.
Thanks in advance
Dirk
 
Re: lsass.exe CPU >90%

How many users do you have ?
lsass is used on dc to authenticate ad users & co.

In this subdomain we have nearly 3000 userids.
This server is DNS Server, too.
Memory 784MB.

Re: lsass.exe CPU >90%

Hi Dirk,

One of these articles may help you as they all refer to your lsass high cpu
symptom. Unfortunately while they do refer to Windows 2000 Server they do
not mention what SP level they apply to.

Re: lsass.exe CPU >90%

Check out this, which is how to troubleshoot high CPU on Win2k. Also
mentions ADPERF.exe which you should use...
