I'm trying to work out why I sometimes get such slow performance on
this Quad Core Q9450 2.66 GHz, 4 GB, running XP Pro. I just ran
Process Monitor (ProcMon) and even though I'm not actively *doing*
much in any of the applications currently loaded, I see hundreds if
not thousands of the following types of entry dominating activity.
What are they and do they offer the experts any clues please?

Process = Isass.exe, PID = 804

Operation Path Result

ISASS.EXE or LSASS.EXE

LSASS.EXE, executed from %windir%\system32 is normal, and safe.

ISASS.EXE has a very high probability of being malware !

Sasser is DEAD.

There are other I-worms that may exploit LSASS via TCP port 445 but the Lsass worm is
dead.

At this point we do NOT know that the PC is infected. I have only stated the if ISASS.EXE
is found it can be malware. Many trojans use that name and are not I-worms and definitely
not Sasser.

Thanks all and my apologies for mistaking Lsass.exe for Isass.exe.
That 'l' looked like a capital I to my tired eyes!

With that cleared up, can anyone offer any suggestions as to why I am
at times getting such a flood of these Lsass.exe processes please?

Are there any yellow question marks in Device Manager? Right click on
the My Computer icon on your Desktop and select Properties,
Hardware,Device Manager. If yes what is the Device Error code?

Are any devices malfunctioning? Select Start, All Programs, Accessories,
System Tools, System Information. Open Components under System Summary
and click on Problem Devices. Is anything listed there?

Have a look in the System and Application logs in Event Viewer for Errors
and Warnings and post copies here. Don't post any more than 48 hours ago.

You can access Event Viewer by selecting Start, Control Panel,
Administrative Tools, and Event Viewer. When researching the meaning
of the error, information regarding Event ID, Source and Description
are important.

A tip for posting copies of Error Reports! Right click on the Report in the
list and select Properties. In the window, which appears are three buttons
towards the top right of the window. The top one has an arrow up, underneath
is an arrow down and third is a button resembling two pages. Click the
button and close Event Viewer. It is not obvious but this action places a
copy of the report in your Clipboard. Now start your message (email) and do
a paste into the body of the message. Make sure this is the first paste
after exiting from Event Viewer.

Try HD Tune only gives information and does not fix any
problems.

Download and run it and see what it turns up. You want HD Tune
(freeware) version 2.55 not HD Tune Pro (not Freeware) version 3.00.

Select the Info tabs and place the cursor on the drive under Drive
letter and then double click the two page icon ( copy to Clipboard )
and copy into a further message.

Select the Health tab and then double click the two page icon ( copy to
Clipboard ) and copy into a further message. Make sure you do a full
surface scan with HD Tune.

What is your motherboard make and model?

"lsass.exe" is the Local Security Authentication Server. It verifies the
validity of user logons to your PC/Server. It generates the process
responsible for authenticating users for the Winlogon service. This process
is performed by using authentication packages such as the default
Msgina.dll. If authentication is successful, Lsass generates the user's
access token, which is used to launch the initial shell. Other processes
that the user initiates inherit this token.

If you are seeing a lot of activity from this process it can sometimes mean
that you have a Trojan or malware allowing access to your PC from the
internet.

Conversely some Antivirus programs regularly check files, folders and the
registry, and each time it does that it will generate an authentication
request.

Any software on your PC that accesses the registry will also generate an
authentication request whenever it does it.

Unfortunately, there are too many different reasons to give you a definitive
answer.

OK, I've installed it. But can you confirm that you're suggesting I
use the SCAN tab, not the default BENCHMARK? My main drive is 750 GB
and I also have another identical one for backups, plus an external
1TB drive. I suspect even the first (C:) will take a long time, so
I'll do that overnight.

Thanks Alister, appreciate your help.

Both Spybot Search & Ad-Aware consistently report no critical
problems.

But I do have AVG (Free) installed and I often see much activity in
Task Manager for various AVG services. In the AVG user interface there
seems no way to toggle its various elements on/off in order to test
it. So I'm experimenting with AutoRun for this.

Meanwhile, before I do any scans, here are the pastes you requested
from the Info & Health tabs respectively. One initial query that's not
directly related to my post is why my two HDs are not running under
UDMA Mode 7. Whatever that is, I assume it's faster?

I am struggling with the Event Viewer reports. Found similar reports but not
many identical. I found your post last January.

What is your version of Windows XP -Home, Professional or whatever?

Can you please check the StartUp type for the services mentioned below.

Select Start, Control Panel, Administrative Tools, Services and right click
on Com + Event System and select Properties. The StartUp type should be
Manual.

Repeat for System Event Notification. The StartUp type should be Automatic.

Repeat for Com + System Applications. The StartUp type should be Manual.

Repeat for DCOM Server Process Launcher. The StartUp type should be
Automatic.

Would you please check C:\Program Files\ComPlus Applications and advise
details of any applications listed there. You may not have any. Make sure
you are able to see Hidden System files.

Some solutions to similar errors refer to unregistering MobSync.exe.
However, I suggest we sit on that idea until we see what is revealed by my
earlier questions.

The reports from HD Tune are fine. With these Event Viewer reports I do not
think a surface scan is required. It would take quite a time. Benchmarking
is not needed.

[Totally meaningless to me I'm afraid!]

Try HD Tune only gives information and does not fix any
problems.

Download and run it and see what it turns up. You want HD Tune
(freeware) version 2.55 not HD Tune Pro (not Freeware) version 3.00.

OK, I've installed it. But can you confirm that you're suggesting I
use the SCAN tab, not the default BENCHMARK? My main drive is 750 GB
and I also have another identical one for backups, plus an external
1TB drive. I suspect even the first (C:) will take a long time, so
I'll do that overnight.
Select the Info tabs and place the cursor on the drive under Drive
letter and then double click the two page icon ( copy to Clipboard )
and copy into a further message.

Select the Health tab and then double click the two page icon (
copy to Clipboard ) and copy into a further message. Make sure you
do a full surface scan with HD Tune.

I am struggling with the Event Viewer reports. Found similar reports but not
many identical. I found your post last January.

What is your version of Windows XP -Home, Professional or whatever?

Can you please check the StartUp type for the services mentioned below.

Select Start, Control Panel, Administrative Tools, Services and right click
on Com + Event System and select Properties. The StartUp type should be
Manual.

Repeat for System Event Notification. The StartUp type should be Automatic.

Repeat for Com + System Applications. The StartUp type should be Manual.

Repeat for DCOM Server Process Launcher. The StartUp type should be
Automatic.

Would you please check C:\Program Files\ComPlus Applications and advise
details of any applications listed there. You may not have any. Make sure
you are able to see Hidden System files.

Some solutions to similar errors refer to unregistering MobSync.exe.
However, I suggest we sit on that idea until we see what is revealed by my
earlier questions.

The reports from HD Tune are fine. With these Event Viewer reports I do not
think a surface scan is required. It would take quite a time. Benchmarking
is not needed.

Thanks Gerry. I'll report back with answers tomorrow.

XP Pro, SP2.

Yes.

No such Service! I know from my old notes that I used to have it, in
between 'SSDP Discovery Service' and 'System Restore Service'. Where
can it have gone? Is this definitely included with XP Pro?
Repeat for Com + System Applications. The StartUp type should be Manual.
Click to expand...

Yes. (It's currently Stopped; is that OK?)
Repeat for DCOM Server Process Launcher. The StartUp type should be
Automatic.
Yes

Folder is empty. (Nothing is hidden.)

If we're talking about the same thing then, yes, I tracked down an MS
article suggesting running this:
regsvr32 "%systemroot%\system32\mobsync.dll" /u
I did so anyway, from the RUN box! What would be the corresponding
command if I need to reverse it please?

And in Event Viewer this morning there's another batch of 16
'Warnings' identical to those on 28th April that I reported. The time
stamp is 15:11. And under System I see one warning at 15:08:

Event Type: Warning
Event Source: Tcpip
Event Category: None
Event ID: 4226
Date: 29/04/2009
Time: 15:08:17
User: N/A
Computer: TERRY-INTEL
Description:
TCP/IP has reached the security limit imposed on the number of
concurrent TCP connect attempts.

But my system doesn't seem noticeably sluggish at present. So we're
dealing with a one-off or intermittent problem. Still an incredible
number of those Lsass.exe entries in ProcMon, FWIW. But from Alister's
reply I gather these could be perfectly valid and no source of
concern.

System Event Notification
http://www.blackviper.com/WinXP/Services/System_Event_Notification.htm

Will need to check what is needed to get it back.

I have some work to do today so my available free time for research is
limited until later.
Click to expand...

Thanks Gerry, appreciate your help. No hurry anyway - I reckon this
will take some time to sort ;-)

I had tried the Black Viper site (and quite a few more) but so far
I've found none that mention the ABSENCE of this service from the
list.

Yes, it is.

It was manual, now auto.

I had this disabled. Is it needed for a stand-alone user? Meanwhile,
I've set it to auto.
What firewall are you using?

The built-in XP version.

Select Start, Control Panel, Administrative Tools, Services and right
click on Distributed Transaction Coordinator Service and select

I had it disabled (another one of those recommendations I'd read).
After setting it to Manual I couldn't start it, but after looking at
its dependencies I changed Security Accounts to Manual Started and
then I could start Distributed Transaction Coordinator Service.

Click to expand...

But after closing & restarting Services, System Event Notification is
still missing.

And I'm now back to that sluggish performance, with many Lsass.exe
entries again displayed in Process Monitor.
