I have a lab full of Windows 7 Pro clients attached to a WSUS server. The clients are attached through a GPO which provides all of the WSUS settings. Periodically, some of the clients will fail to report in to the server and will remain that way until acted upon. If I were to log into one of the failing clients and run the Windows Update software, an 80070005 error is produced, but the client reports back in to the server.
Why do some of the clients drop their connections to the server? How can this be prevented and what can be done about the 80070005 error? My research thus far has told me that the error comes from the update software not having the proper rights to actually update Windows. I have seen some pages that suggest resetting the ACL on the main Windows registry, but am hesitant to do that for obvious reason.
Any thoughts toward this end would be greatly appreciated.
