ntds to bring up Active Directory, as well as its dependencies.
Now, what's the old‑school analog?
That would be Directory Services Restore Mode.
And what we'll need to do there is, this is just one way to do it,
go to msconfig.
I mean,
I remember the days of rebooting a domain controller and then
having a keyboard there and hammering on F8.
I mean, ain't nobody got time for that.
Especially when every minute of unavailability counts for these
machines and you have service level agreements attached to
these machines and their services, much better to be very intentional.
So MSConfig, also known as system configuration,
allows us to be very intentional on the boot page here and say,
let's do a Safe boot for Active Directory repair.
This way, we're guaranteed that upon system restart,
we'll go into Directory Services Restore Mode.
So let's click OK and hit Restart to start that process.
All right, well, I'm back from the restart.
I actually was having some problems getting into
Directory Services Restore Mode,
so I figured the next best thing would be to just show you.
I mean, not that there's anything dramatic to see.
All you have is the Advanced Boot Options going into DSRM,
and then you're given a Command Prompt from which you can run your commands,
just exactly like I showed you, with Restartable AD DS.
You'll want to make sure that you come out of MSConfig
mode and that you're restarting normally,
just verify that your Boot is set back to regular,
no Safe boot, just a regular, old standard startup.
Last thing we're going to do here is look at replication.
Specifically, let's kick the tires a bit with repadmin.
Like I said, /?
gives you some nice help.
You can always do a repadmin and then pipe that to a text file.
That'll give you a print of all that.
But you can go online too.
I mean, that's not that great of a recommendation.
How about, show replsummary and see what's going on.
Now, as I showed you at the beginning of this demo,
let's see, total percent error, okay,
so I've got some communications happening here.
I've brought up MEM1, which is my second domain controller in this environment,
about 25 minutes ago,
so it makes sense that the delta here is that amount of prize.
We've got some issues here, maybe a network‑level error.
Let's take a look at some additional flags, like replsummary was good. How about showrepl?
