How to fix FRS is deprecated error
If you are trying to promo windows server 2019 as domain controller, it happened “Verification of replica failed. The specified domain {Domain-Name} is still using the File Replication Service (FRS) to replicate the SYSVOL share. FRS is depreciated.” Error, this is because Windows Server version 1709 (or after version) can no longer be added as an Active Directory domain controller (DC) to an existing domain that is still using File Replication Service (FRS) for replication of the SYSVOL share.
