Add-KdsRootKey –EffectiveTime ((get-date).addhours(-10)); 

4. Create the Managed Service Account as required.

New-ADServiceAccount -Name VCsrv -DNSHostName dc.lab.home -Enabled $true -path "CN=Users,DC=lab,DC=home"

5. Assign the MSA to the computer account.

Add-ADComputerServiceAccount –Identity “vc” –ServiceAccount  VCsrv
