I recently had to reinstall WSUS 3.0 SP2 onto an SBS 2008 server which became horribly messed up. I followed the SBS 2008 Repair guide and some notes of my own here and then applied WSUS 3.0 SP2 over the top of it. That was great, but then I had issues with the existing clients not being able to check in to the SBS 2008 server. They all gave error 800B0001 when you tried to do an update. That issue is covered of with a Microsoft Update available MS KB 2720211 here – but wait – don’t go downloading that just yet. You see – this SBS 2008 server now has a Windows Server 2012 and Windows 8 machine in the network as well – so you will need to apply this update MS KB 2734608 you can download it here. Now THAT is the update you want to get as it includes the MS KB 2720211 as well.
Installing it is simple – apply MS KB 2734608 and reboot the server. Then you are good to go. If you have Windows 8 or Windows Server 2012 servers that were reporting into the WSUS server BEFORE you installed the update then you will also need to do the following;
- On the affected client, open cmd.exe in elevated mode
- Type the following commands. Make sure that you press Enter after you type each command:
Net stop wuauserv
rd /s %windir%\softwaredistribution\
Net start wuauserv
