[Autogenerated] Hi there. Welcome to the
next month in our costs. My name is Mike
Brown. On this next model will be looking
at trouble shooting domain controller
deployments. We're gonna start off its
module by discussing the importance of De
En esto actor director Debate Service's
before troubleshooting some common D. N s
issues, particularly around the
registration of SRV records. Well, then
take a look at Global Catalogue Service,
discuss what they are and why they're
important Tragic directory before going on
to discuss Operation Master rolls on
managing and troubleshooting Operation
Master rolls. So let's start with
disgusted active directory Andi its
relationship with the N s so Dennis itself
is that resolve names? Why _______?
There's all sorts of registrations that
computers commit against the NS for active
directory. The important record type is an
SA ve record or service record. These are
records that debate controllers register
of de en esto adverse eyes. The active
directory service is that they offer
members of our domain think we're Deanna's
to locate. The service is service is like
curb Russ Elder Im Global Khaleq Service's
are all registered by two been controllers
Indian s members of our demand then
queried. The address for the service is
Devyn. Controllers also used Vienna's Tok
the I P address of their replication
partners so that when they have a change
you to replicate their partners, they
couldn't form the pattern off. That change
on the partner can pull that change down.
So without Deanna's domain controllers
would not be a Register Records on men's.
The domain would not be able to clear if
those records what could go on well s I V
records might not get registered domain
members then would not be a location list
of tubing service. SRV records might not
get updated. When did Ben controllers
change the service? They offer again,
meaning that members won't better find the
correct service on the corrective and
Controllers I general failure the dinner
service would be in. Our members won't be
a queer for our records. So Dennis is
violet important for a healthy, active
directory deployment. Let's take a look at
the N s deployed to our environment. Let's
leave this server car remote desktop
connection and go back to my desktop Buck
on the desktop and served manager. We can
see R. Two D. C's Remember, we've got the
marks of admin tools installed. So any
rules that only de ces we should be a
manage remotely. I'm not include Dennis.
If we right click one of these D C's and
then select Deanna's manager Deanna
Spanish opens up, we should be at sea
Bullfighter Men controllers because they
both of the innocents, told now what we're
looking for. If the company dock Pierre, I
forward look up zone. So if we never get
fruit Fault observes, we should find
commit a pair I on inside their whole set
of records He was he d. C and D C. Two on
the fact that they have registered their
name twi pairs mapping this and that's
great if want to connect these two demand
controls by name, but in order for member
service client machines on applications to
discover active directory domain service
is these two demand controllers need to
actually SRV records as well. So, beneath
coming up here, I if we take a look at the
underscored TCP symptom in, we can see
that both d. C and D. C. To have wretch
themselves a global Catholic service. We
can see that that both offering curb
service is as well as elder connection
points. If we take a look at the sub
domain under skull sites on Select Default
first sight name on underscore TCP
default. First sight name is the default
name for the first active directory site
that's created. This was created by the
active directory promotion process. We'll
be working valedictory sites, let on this
costs, but for now, think of them as being
a physical power of your network. Beneath
this site again, we can see records that
be registered by our demand controllers.
Once we start having mobile site, each
turbine controller will register records
beneath the sites that their members off.
This looks good. My machines are
registering the SA ve records
appropriately that this is Mike's off
Dennis. What if you use 1/3 party in a
service, maybe even a steak service, where
you have to register record manually?
Well, you'll need a list off SA ve
records. Luckily, we can find that list of
records Well, not the band controls. If we
closed Dennis Manager, select D. C. And
again we'll open up a remote desktop
connection on D. C. Domain controller. If
we never gate to Dr C. Windows System 32
and come pick in this direct. We find lots
of useful files Right now. We're
interested in net leg wound up D N s. If
we right. Click this and open this in note
pad. And here we can see a list off. SA ve
records. These are the records are
registered by this machine. Indian asked.
But if you're using 1/3 pie or stacked
Deanna system, these are the records you
would have to add manually. Take a minute.
Just go from this list. You can compare
this list directly with the records
registered in our D. N s. A. I'm gonna
leave this connection now and go back to
my desktop back on my desktop and still
you serve a manager. I'm gonna go back to
D. N s manager now. Indiana Spanish Jer
with the tool maximized. We're gonna take
a look up Cos up pr I again so slight Ford
pickup zones. It's like to compete a p r i
and this time want to right click coming
up here. I on got properties. We could see
several things. First of all, that it's an
active directory in grade zone. This means
that Dennis Information is starting
application partition of Active directory.
This is a good thing. It means that dance
information that's replicated will
replicate securely. We can see that this
Dennis information is gonna replicate Old
unit serving the demand. Anime conceits,
dynamic updates, stares. Right now, the
zone accepts dynamic updates from
anywhere. What you can do is change the
dynamic updates to secure only I change
into secure. Only this Deanna Soon will
only accept updates from trustee machines.
Season apply will save those changes just
like our domain service's works in a multi
master model. So too, does that active
directory that great zone. This exact same
information that we can see here on D. C
is also replicated to D. C. To we can
never get food there. I'll also see
comprende up p r I and all its records.
The change made to one day on a server
will be replicated on the other. They
should be in that your D n. A service is
highly available. There's little point
having multiple domain controllers on,
then only one day in a servant. If the
Dennis ever failed, you'd lose access to all these records
