Hi All, 
  
We have SCCM 2012 R2 Server, We have been using more than a years , 
Now im facing crazy issues . 
  
1.every month we using sccm server for deploying windows patches  . 
2.before patching we set maintenance schedules for device group. 
3.patch deployment is working fine without any issues and we get the success 100 % compliants report in all the server . 
  
Note:- but after one or two months later  in Monitoring-->deployment tab-->its showing only few machines success results or deploying again old package'' 
this process is keep on rotating in all the deployment . 
  
  
  
how to resolve this issues. 
  
Regards, 
Velu M
