I have a Win2000 Domain Controller and have had this problem since July. I
just happened to come across a fix that finally worked for me. If you have a
domain controller, load up active directory users and computers. Under the
Users group, there will be a Domain Guests object. Right click on this,
select properties and then select the members tab. If the user that you log
into the domain controller with is in this list, remove it. Log out and back
in again and hopefully the windows update will be working. It did for me.
Besides the Domain Guests, also look in Users and Guests. Hope this works.
