Disable and stop the DHCP Server service on all impacted domain controllers:

• Open the Start menu, type “Run,” and press Enter.
• In the Run dialog, type “services.msc” and click OK.

4. On the Remove server roles page, uncheck the box next to “DHCP Server.”
5. Click “Remove Features,” then hit “Next.”
6. On the Remove features page, click “Next” again.
7. Click “Remove” to start the uninstallation.
8. Once the process is finished, click “Close.”
9. Repeat these steps for each affected domain controller.
