First using ADSIedit.msc dig down into CN=Computers( or OU=Domain Controllers if you’re naughty), find the system and verify that Authenticated Users have read permission for CN=DFSR-LocalSettings. If not give it to them.
Then from the command prompt in %windir%System32wbem
net stop winmgmt
net start winmgmt
net start iphlpsvc
net stop dfsr
net start dfsr
And for good measure go ahead for force a Group Policy Update(gpupdate /force)
After all this run another health report. If this doesn’t help try the next google result.
