Hi Anan,
We are proposing active directory offline defrag activity and would be carried after BAU hours, that is 8:00PM server local time.
There will be no impact on file/print and DHCP services during implementation. Hence please approve during non-business hours in week days.
We are taking the Backup of Virtual machine folder for VMs which will enable us to restore the DC with minimum time in case of any issues
Impact :- Users may experience little bit slowness during user authentication
Below are the servers that would be involve in the activity.
