LsaSrv SPNEGO 40961 error leading to system freeze under XP Pro SP2

I have a Dell Inspiron E1505 system w/ dual core intel processor.  1 GB memory, 80 GB HD.  Radeon x1300 video card.  Running XP Pro SP2 with all security patches up to date.  

I had a hard drive fail last week and Dell replaced it.  After reinstallation of all oftware, with the only new program being Microsoft OneCare for virus, spyware, etc (My TrendMicdo subscription just expired), I have had several lockups of the system.  The screen freezes, no blue screen, no error messages.  Just a total lock up.  Nothing consistent about what program I am using or anything between the different lockups.  

After talking to Dell, we found several entries in the system event viewer around the times of the lockups.  It referred to the source as being LsaSrv and event being 40961 with a category SPNEGO.  

I have googled this problem, searched the MS support database and checked here and have found similar errors, but not a similar result (freeze of the system).  

As I noted, the only different program that I have installed is OneCare Live, but I found no other users having a similar problem.  Any suggestions on solutions?

We fight this one all the time - 'authentication' 40961 and lsasvr.

From 'My Computer' Properties, drop the computer down into a Workgroup (DO NOT RE-BOOT).
Immediately go back in and re-add the computer to the Domain.


Stop and re-start the w32time service - and make sure it synchronizes time with the DC.

We have written a batch command at work with the steps below imbedded.
It seems to work for us.

To configure a client computer for automatic domain time synchronization

 1.  Open a Command Prompt.

2.  Type the following command and then press ENTER:

w32tm /config /syncfromflags:domhier /update

3.  Type the following command and then press ENTER:

net stop w32time

4.  Type the following command and then press ENTER:

net start w32time

Check the local workstation Event Viewer for Event ID 40961 or 9 - or anything else that relates to 'authentication errors'.
Make sure the boxes are not going into any kind of 'sleep' or hibernation mode.
Shutting down the monitor is fine, I never advise any automatic action with the CPU.

Any Terminal Services functions/connections?
When users logged into a terminal server and terminal sessions were disconnected (but not terminated).
Improperly terminating those connections will create the same symptoms.

So, this error can occur even when the system isn't logged into any network?  I have had it happen when connected to my wifi at home and then connected to the wired office network.

Just confirming before going through the steps
The use of OneCare Live bothers me also. I tried it for a few days last year, but had a lot of 'glitchy' type problems with it. Nothing big, but just seemed to be interfering with the OS.

The 'sleep or hibernate' mode created a lot of problems for use and we disabled it on all computers on our domain.

Compare the times in your Event Viewer logs for this event. Are you getting them while at home or just when you are wired at work?

The problems are happening both at home and at work.  I am going to try the first possible solution and also uninstall onecare and go with what I know works.  

OK - if you are going to drop it to workgroup and re-add --- MAKE SURE you are at work and hard wired to the domain.

So far since uninstalling OneCare Live (I have not attempted the other steps), I have had no lockups in nearly 2 days
Amazing isn't it (One Care)?
Their own product and it interferes with their own OS.
I had it on my personal notebook last year and thought it might just be because of all the misc junk I have installed there.

BTW - were you running any other 3rd-Party Security programs at the same time as One Care?

I was waiting to report until I had several more days of crash-free living.  So far so good still.  

Apparently, Vic, as you noted, OneCare messes up MS' own OS.  Quality work.  

No, I wasn't running any other security programs at the time.  

Anyway, I think we can call this closed.  Thanks for your help.  
Thank you.
