Upon visiting Windows Update or Microsoft Update I receive an error msg that
states:

Files required to use Microsoft Update are no longer registered or installed
on your computer. To continue:
Register or reinstall the files for me now (Recommended)
Let me read about more steps that might be required to solve the problem

So I click on Continue while using the Recommended setting, and after the
browser downloads and registers it's software automatically, it re-routes to
the same webpage to register or reinstall the files.

I have searched numerous help sites before posting on this newsgroup.
I was told to re-register msxml3.dll which fixes most problems. However I
was unable to register using "regsvr32 msxml3.dll" (without the quotes of
course) since I receive an error:
DllRegisterServer in msxml3.dll failed. Return code was: 0x80070005. This
happens whether I use it before or after the command: net stop wuauserv.

I have searched and found nothing new regarding the above mentioned error.
Every site suggests to re-register msxml3.dll. I am unable to do that.

Another thing I've noticed is that when IE 6 re-routes me to the page where
I have to register or reinstall files, it goes through a page that has the
url with error number 2146827859. I have searched errors regarding this for
Windows Update and found out that it refers to
0x800A01AD -2146827859 ActiveX component can''t create object.
However this does not have the same Regsvr32 error code.

I am running Windows 2000 SP4. I have managed to install all updates upto
month of October.

Please help me figure out how to fix this problem without having to
reinstall anything.
