Maitanance Plan fails with error:Alter failed for Server 'servername'.

Hi , Today morning i saw my maintenance plan job to do differential backups got failed and i saw the error

Alter failed for Server 'servername'., oops i never saw this error , tried  goggling and found some help

so what happened was my Windows team  changed the CPU I/O Affinity settings and which made the changes to SQL Server

So to get your any maintenance plan running go ahead and run:

    sp_configure 'allow updates', 0

    reconfigure with override

and execute the Maintenance Job , it will run successfully  

Thanks
