Automatic updates stopped working after SP3 has been installed

We have a corporate WSUS server that all workstations use for getting
updates.

After installing SP3 on a new Windows XP box, that box stopped getting
updates. Its WindowsUpdate.log contains SOAP errors:
I've tried to delete SusCliendId from workstation's registry,
SoftwareDistribution folder from workstation's Windows folder - nothing
helps.

All other workstations in AD domain are updating from that WSUS server
perfectly.

Try this.
net stop wuauserv
net stop bits
rename the c:\windows\software distribution folder
net start bits
net start wuauserv

If this doesn't fix it, then force a reinstall of the agent by downloading
http://download.windowsupdate.com/Wi...one/7.1.6001.6
5/WindowsUpdateAgent30-x86.exe
and installing with the /wuforce switch

I suppose, this is a problem on a server side, since it looks like a
duplicate key in database:
2008-06-03 15:07:46.561 UTC Error w3wp.6 ClientImplementation.SyncUpdates
System.ArgumentException: Item has already been added. Key in dictionary:
'19202' Key being added: '19202'
at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean
add)
....

If you have any other suggestions, please, let me know!

How about this:
net stop wuauserv

Delete the following registry keys:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\PingID
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\AccountDomainSi
d
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\SusClientId

net start wuauserv
wuauclt.exe /resetauthorization /detectnow

Is this the ONLY client machine that has this problem?
Most of the time this is a WSUS server side problem, but that would cause
all of your clients to fail.
How many computers check into your WSUS server?

OK, well lets try the shotgun approach to see what happnes. Run my tool
from:
http:\\www.codeplex.com\aureset

Just tried your suggestion. Since there are no PingID and AccountDomainSid,
I've deleted SusClientId only.
Not helped either

Looks like I've discovered the sequence of actions that led to the current
issue:
1. After installing SP3 warnings and soap errors came up
2. One of our IT support guys deleted SusClientId instead of removing
SoftwareDistribution folder
3. And now nothing helps

Any other thoughts?

It appears, there are two more clients that have such a problem: Windows
2000 SP4 and Windows XP SP1.
In total, there are approx. 50 computers that use WSUS server.

This didn't help unfortunately. Do you need me to send generated log files
somewhere?

Please, mention, that couple of antiviruses thinks your software is a virus:
http://www.virustotal.com/analisis/e...f8502edd0fa454

Are the machines getting the error below on the same network segment as
those not getting the error?
( WARNING: SyncUpdates failure, error = 0x8024400E, soap client error = 7,
soap error code = 400)

The logs that the tool generates probably are not going to help with this.
I think at this point we would have to get a network trace and have you
open a case with us so we can really dig into it.

Thanks for the VirusTotal link. Thats interesting. I can see how what it
does would look suspect.

I have the same problem:

WindowsUpdate.log shows:
WARNING: SyncUpdates failure, error = 0x8024400E, soap client error = 7,
soap error code = 400, HTTP status code = 200
WARNING: SOAP Fault: 0x000190

SoftwareDistribution.log shows:
Error w3wp.5 ClientImplementation.SyncUpdates System.ArgumentException:
Item has already been added. Key in dictionary: '8135' Key being added:
'8135'

Nothing helps, already tried:
1) wuauclt.exe /resetauthorization /detectnow
2) Deleted SoftwareDistribution Folder
3) WindowsUpdateAgent30-x86.exe /wuforce
4) Deleted SusClientId and Validation Registry Keys

It looks like a server side problem...

Any help is appreciated!

The problem on the server side with declined (!) "Office 2003 Service Pack
1" update.
I've solved it by redecline the update.

Redecline (aprove and decline) the now declined update "Office 2003 Service
Pack 1" on the server side.

How do I reset Windows Update components?
