Windowsupdate.log ERROR CODE= 0x80072EE2, Endpoint protection not updating.

Problem: 

                We had installed JAN'2016 patches on SCCM server and WSUS server, after reboot, we got below error on all servers and workstations,

                 Microsoft end point protection not updating, error getting updates not required/applicable, even though updates are missing.

SOLUTION:

we ran below command on both SCCM and WSUS Server,

wuauclt /resynchronize /detectnow /reportnow

it took few hours to take effect. and updates are started working flawlessly.
