We installed new Windows 8 clients into our existing domain and sadly found, that they cannot update themselves from our Windows Server Update Services (WSUS) server, which works perfectly with all other existing clients. Although the Windows 8 patches were enabled on the WSUS server, the update always failed with 0x8001b001 error code.
The solution is quite simple, just install a recently released update to the WSUS server:
- Update for Windows Server Update Services 3.0 SP2 for x64-based Systems (KB2734608)
- Update for Windows Server Update Services 3.0 SP2 for x86-based Systems (KB2734608)
You can read more about the update in the KB2734608 knowledge base article.
We had to restart the WSUS server as well as the clients, but after that the Windows Update process completed successfully on the Windows 8 machines.
