Hi Bob - Just to supplement Kayman's comments (the Update Agent 3.0 and
KB927891 are the right first step):
In a few case to my knowledge the lockup has returned. It's thought that
this is probably due to a recurrance of corruption of the DataStore.edb
and/or the log files in the
%windir%\SoftwareDistribution\DataStore
folder probably caused by interference by an AV scan during the Update
checks. If this does occur for any of your machines, you might wish to try
the following work arounds to the particular machine to get things back to
normal.
1. Defrag the DataStore.edb file using the following command line:
esentutl /d %windir%\SoftwareDistribution\Datastore\datastore.edb
2. If that doesn't do it, then try recovery of it:
esentutl /r %windir%\SoftwareDistribution\Datastore\datastore.edb
(Hopefully this will get all databases to a
consistent state)
3. If that doesn't help, then try a Repair:
esentutl /p %windir%\SoftwareDistribution\Datastore\datastore.edb
If those steps don't solve it, you can try the following procedure which I
worked out with some MS personnel which so far has worked when used:
The following assumes you're on Windows XP but will work OK for Win2k as
well. If you're confident about what you're doing, then try the following
first - only if it doesn't work, then there's another level of stuff that
can be done following:
1. Stop and Disable Automatic Updates, Background Intelligent Transfer
Service and the Cryptographic Service.
2. Rename the folder %SystemRoot%\SoftwareDistribution to
%SystemRoot%\OldSoftwareDistribution
3. Open Notepad and create a file containing the following:
REGSVR32 WUAPI.DLL
REGSVR32 WUAUENG.DLL
REGSVR32 WUAUENG1.DLL
REGSVR32 ATL.DLL
REGSVR32 WUCLTUI.DLL
REGSVR32 WUPS.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUWEB.DLL
Save this file as 'Wudll.cmd' (without the quotes) to any convenient
location then exit Notepad and double click on the file you just saved. You
should get a 'Sucess' mesage for each of the .dll's listed above.
4. Now Re-enable to Automatic status and then Start each of the services
you stopped before - Automatic Updates, Background Intelligent Transfer
Service and the Cryptographic Service.
5. Now Reboot. Now Reboot Again. (Yes, twice.)
See if that solves it - give it a couple of days. If so, then you can
delete 'OldSoftwareDistribution'. I would request that you post back with
your results. _Only if the problem does re-occur_, then do the following
_exactly_:
1. Go to http://wiki.djlizard.net/Dial-a-fix and download Dial-a-fix
v0.60.0.24 (2006-10-27) Here's a direct download link:
http://djlizard.net.nyud.net:8080/software/Dial-a-fix-v0.60.0.24.zip and a
secondary: http://djlizard.net/software/Dial-a-fix-v0.60.0.24.zip from
that page's download section, here:
http://wiki.djlizard.net/Dial-a-fix#Mirrors.2Fdownload_locations.2C_and_articles .
2. Unzip it to a new folder at root with any name, e.g.
c:\Dial-a-fix-v0.60.0.24
3. Restart the computer in Safe Mode. Now double click on Dial-a-fix.exe
in that folder.
4. Click on the following:
- Options/tooltips (just to get an idea of what it does in each
section.
:) )
- Both boxes under Prep
- The 'all' (top) box for Sections 2 (section 2 will be blanked in Safe
Mode), 3 and 4 (which will automatically be set when you check 3)
- In Section 3 click on 'Flush Software Distribution' and choose 'Yes'
to force the deletion of the folder.
- In Section 5, 'Programming cores/runtimes',
'Explorer/IE/OE/shell/WMP', and 'Object linking libraries (OLE)' only.
- Click 'Go' . (Some of the re-registrations may take what seems like
a
long time for some .dll's - Don't be impatient.)
5. Reboot. Now Reboot Again. (Yes, twice.)
See if that does the trick, and, again please post back with your
experience.
