The recovery depends entirely on what is wrong with Exchange.  Maybe a backup/restore.  Maybe other troubleshooting steps.  It all depends on what's wrong.  You begin to determine what's wrong by referencing the event logs.

Assuming you have a separate domain controller or at least a second one if your exchange server was a domain controller then simply run following command:

Setup.com /m:recoverserver

This will read all data from active directory and rebuild your server.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

To be more specific.

Rebuild the server with the exact same name, reset the computer account in Active Directory, DO NOT delete it.

Join tge rebuilt server to the domain then run the command I posted above.

Then restore your databases.

If you only have one DC and that has exchange on it then the same procedure applies just before you install exchange you will make the rebuilt server a domain controller and then restore the system sate from backup.

Again, making sure the computer names are the same.

But, where ever possible you should have more than one domain controller for this exact reason.

As I already said, above.  If the ONLY DC has failed then you need to do a system state restore otherwise there is no Active Directory to recover exchange from
