Well uninstalling the drivers stop the crashing. Makes the computer a lot slower but stable.

I very dare say that the problem is due to conflicts between WMI drivers with some inplications to user profile permissions. :shock:

I ve tried all I know and imagined.

Anyone, help!

I'm getting the same error messages aswell as sudden application
shutdown and more often than not a complete system shut down...

Is this a device driver problem or a hardware problem as this is a
fresh install of XP and SP2 and the problem is still occuring...

I'm not computer illiterate but some of the error explanations are
way over my head....Anyone able to give me a plain English reason
and cure....


4609 event system Solution!!

I've been seeing a particular problem on certain Windows XP computers when they are updated to Service Pack 2, and judging from posts in these newsgroups and also on other Internet message boards, it's quite a common problem. The symptoms are that after SP2 has been installed, and the machine has been rebooted a few times, this error message appears in the Application Event log.
I searched information on this problem for a while, and eventually found the following two articles relating to Windows 2000 Service Pack 4: M821546 and M827664. It turns out that in Windows 2000 Service Pack 4 two new user rights were added, "Impersonate a client after authentication" (SeImpersonatePrivilege) and "Create Global Objects" (SeCreateGlobalPrivilege). Even though the articles do not say so, it seems that they were also added in Windows XP Service Pack 2. However, it seems that sometimes something goes wrong in the XP SP2 installer when it sets up these two new user rights. I think this is why some computers get the above error messages. It does not happen all the time and I cannot see any reason to which some computers are messed up and some ones are not. I reckon it is a race condition or some other similar bug in the installer.
The reason that the problem does not always manifest itself straight away is probably because by default Windows only “refreshes” its security settings every 16 hours, and if that refresh is a while away you might not see the problem right away. Some networks may also have turned up this refresh time, so the problem is even worse.
Some sites may also have these settings set (possibly incorrectly) in their Default Domain Policy group policy, which could also mess things up. However, at my site we don’t have these settings set on the domain anywhere, only in the Local Security Settings, and yet we still have the problem. Anyway, if the security settings upgrade goes wrong, you end up with the error. Fortunately, it seems to be quite easy to fix.
On the affected workstation:
1) Go to Start -> Settings -> Control Panel -> Administrative Tools.
2) Run “Local Security Policy”.
3) Go to Security Settings -> Local Policies -> User Rights Assignments.
4) Double click on “Create global objects”. The correct default settings are “Administrators”, “INTERACTIVE”, and “SERVICE”.
5) Double click on ''Impersonate a client after authentication''. The correct default settings are “Administrators”, “ASPNET” (if you have the .NET Framework installed) and “SERVICE”.
Even if the settings are set correctly, you may need to “refresh” them to fix the problem. To do this, on each policy, remove one of the entries (“SERVICE” is probably the best to remove), then press OK to save the changes, and then go back in and add it back in again (click “Add User or Group...”, type “SERVICE” into the white box, and press OK). Then close the Local Security Settings box and reboot. If you are running in a domain with Group Policy, you might want to force a group policy refresh before you reboot by running “gpupdate /force”.

Event System error 4609

Found that removing MSN messenger 7.1 from running at boot-up solved this problem for me. hope this helps

for error codes 4609 and 8193

Postby lan_shark » Fri Sep 23, 2005 12:31 am

I bet a 20 oz coke that it's the motherboard. I recently examined a computer that was giving the same problems and had error codes 4609 and 8193. I had enough reason to believe from the start that it was the motherboard from experience. However, I still tried other paths (i.e. disk checks, virus scans, changed ram, changed video card, repair install, etc.) and 5 hours after, found out that it truly was the motherboard.

Amend earlier post. Uninstall msn messenger, clean msn messenger in registry {be careful here} reboot Go to download msn messenger 7.0 not 7.5 sign in to msn messenger you will get 2 popup boxes ,your email in box and box stating download newer version. close box or ignore box prompting newer version. error id 4609 should be gone. It worked for me. Just don't ever download newer version 7.5
