Win2k Server Memory Leak - Need Help

[CBuxton]

I posted this in the OS forum, but haven't gotten any help and I really NEED some!

I've got a memory leak with LSASS.EXE on my Windows 2000 domain controllers. I found THIS artice on TechNet, but I don't believe I have this problem. There are only about 2000 uses on my system, and my largest group is about 900 users. I can't imagine Microsoft's definition of "very large" group is only 900 users, and it's not a built-in group anyway. Where else can I found information about how to fix this problem? LSASS.EXE takes about 25MB of memory upon bootup, and slowly rises to about 40MB, at which point I cannot logon with the administrator profile (gives me a default), and no start menu shows up (no icons..just blank). I reboot and runs for a couple of days and I get it again. This is driving me nuts and I don't know how to fix it. Looks like SP2 will address this issue, and I'm unconvinced that I'm having the same problem. What can I do? Thanks for any help.

Have you checked CPU usage by LSASS.EXE? Are you getting Event ID 5711 in your Event Viewer?

Jaywallen-

I don't have any of those error in the event log, and CPU usage is low >1%

I'm sorry, then. That would rule out the only alternative to the one you've already found -- that I could think of, anyway. I've made a note and will snoop around to see if I can scare up something.

Do you have any other reasons that the feelings about client group sizes to make you think that the Technet article doesn't pertain to your situation? On the surface from my admittedly distant perspective it looks like a good match.

I'll follow this thread with interest, and hope that some more people will kick in.

Regards,
Jim

Thanks jaywallen...the reason I don't think that that issue is what I'm having is the following:
1) it refers to large BUILT-IN groups. The groups that I have that are large are groups that I've created myself.
2) I can't imagine that 900 users is considered "very-large" to Microsoft. It seems that larger companies would have MUCH worse problems that I am having.

I understand, and I think your reasoning makes sense. I do wonder if how you go about creating a group, as opposed to using an inbuilt group, can be a determining factor in such cases.

I hope I'll get to hear how this turns out. Still haven't come up with anything on my end.

Hmmm. It's occurred to me that this thread is flame bait for the Linux crowd. I'm an old AIX guy, myself, but I don't feel like casting stones. In most circumstances I've seen, W2K would make an admirable substitute for the NOSes I've used. But it is still a wee bit bleeding edge at times.
