suddenly i got a problem in my primary domain controller.
i installed additional one and seized all roles in another server now.
but when i tried to uninstall the old corrupted DC then it always refuse and gives the following error message (Failed to detect if active directory domain services binaries were installed. the error was: the requested operation failed. A system reboot is required to roll back changes mode)
by the way i tried to uninstall using the following commands:
dcpromo
dcpromo /forcremoval
dcpromo /forceremoval /uninstallbinaries

but always giving the same error message at the begining of the un-installation process.

If the new DC is running fine (what happens if you shut down your old DC for a couple of hours?) you can consider the option of removing the old DC object from AD manually. This is the only choice when a DC server is declared defunct.

hello dear,

i always turn it off but actually i need it to be uninstalled correctly because all other domain controllers still see some details,also the 4 exchange servers still see it, you have any way to overcome this issue?

On your exchange servers look in the event log for a 2080 message

This will tell you what global catalog servers exchange is looking for.

See if the DC you are trying to remove is in the list.
