wu service hangs @ start_pending, cannot register wuaueng.dll

This problem started shortly after installing SP2. The Automatic
Updates service hangs in start_pending mode and I cannot use the
windows update website. On the website I click yes to install V5,
wait a long time, and get a 0x8DDD0004 error. Wu log has no record
for it either. I read a lot into this and I tried a number of things,
including reinstalling au.inf and re-registering the dlls.

I noticed a problem with the wuaueng.dll, which I can't register.
This is the error I get,

LoadLibrary("C:\Windows\system32\wuaueng.dll") failed - The specified
procedure could not be found.

The file is there, the path is correct, what's the problem? Just for
the heck of it I tried doing the same on my other Sp1 machine, even
though it worked fine, and there were no problems. I tried
transfering the wuaueng.dll from my sp1 machine to my sp2 but the file
still didn't register.

Since wuaueng.dll is causing problems, and everything else is just
fine, my guess is that this dll is responsible for the automatic
updates service not working properly.

Anyone have any ideas on how to fix this problem?

Where are you seeing this? What is the context?

Without any other context my *guess* would be that one of the other
modules involved in the re-registration process are the problem.

I personally would first try using FileMon to see what other modules
are involved in the failure. That isn't always successful since sometimes
the modules involved are already loaded and the failure is in them.
In that case RegMon might give you some more clues.
What would be really nice is something that gives a trace of the modules
and entrypoints, including the one which issued the error message.
I suppose running a debug version under the Visual Studio IDE
could show you that but I have never done it.


If you aren't interested in trying to diagnose the problem further
I would start with

sfc /scannow

as an attempt to make it go away.


Good luck
