It’s single domain environment with 3 DCs, 2 DCs are running Windows Server 2008R2 and one is running with Windows Server 2003.
Planning to decommission Win 2003 Domain controller.
Below is the plan. Please have a look, correct if any steps going in wrong manner.
- Changing Domain controller DNS IP which is planned for decommission from all the Systems, to with available DNS servers.
- Changing the DNS IPs hard coded in Applications and correcting the DHCP scope DNS settings.
- Transferring FSMO roles from this old server.
- Check the health status of the Domain replication. If it is good.
- Stop the replication on DC Windows 2003 (inbound and outbound)
- Disable the NIC card.
- Shutdown it for 1 week and monitoring it. -==> is this cause any issues except replication, tombstone period is 1 Month for this domain.
- If there is no issues found.
- Demote the server from Domain & clean the metadata using the ntdsutil tool.
