My WSUS was working fine until today, when I get an error code 800B0001 , an error occurred while checking for new updates for your computer.
After long hours of searching, finally discovered I need to install Windows Server Update Services 3.0 SP2 patch, KB2720211
Rebooted WSUS after patching & WSUS works like charm!
