However, once I join it to the domain it cannot perform windows update.
I get the following error code Validating signature for C:\WINDOWS\Software Distribution\Self Update\wuident.cab: Microsoft signed: Yes Infrastructure signed: No WARNING: Digital Signatures on file C:\WINDOWS\Software Distribution\Self Update\are not trusted: Error 0x800b0001 WARNING: Self Update check failed to download package information, error = 0x800B0001 FATAL: Self Update check failed, err = 0x800B0001 WARNING: Skipping scan, self-update check returned 0x800B0001 WARNING: Exit code = 0x800B0001 After you joined the Domain, can it still list the updates with the KB hotlinks for manual download or does it fail to even get that far?
This issue occurs because the imaged client computer has a duplicate Sus Client ID value in the registry.
To resolve this problem, you must clear the Sus Client ID and Sus Client IDValidation registry values.
For a list of supported client computer operating systems and software requirements, see WSUS client system requirements.
When Automatic Updates checks for updates, it also checks for and updates itself.
With the proper configuration, these computers can always download approved updates from the WSUS server that is nearest to their current connection point.
The instructions in this topic assume that the network has several different DNS subnets, and that you will install WSUS servers in the subnets.
For more information about domain-level security, see Local and Domain Default Groups.If you want to refresh Group Policy sooner, you can go to a command prompt on the client computer and type in a console with Administrative permissions: gpupdate /force.NOTE: If you are running your own domain, when you configure the Group Policy settings in Active Directory for WSUS, use a Group Policy Object (GPO) linked to an Active Directory container appropriate for your environment.I'm not asking just to hint that I know your answer, this is for myself to help me and others avoid the time consuming precaution of imaging my box, joining a domain just to realize there is no more way to even dowload the fixes that I'm willing to individually click and load or if Windows UPdate is just ruined until I restore my image.This could be that WSUS needs to be updated to manage Windows 8 clients.
