[Autogenerated] Welcome back to date.
We're diving into managing DNS server with PowerShell.
So we always know it's DNS, right?
But with PowerShell, you can make managing D NSA little bit easier.
So why should you be excited about using PowerShell for DNS?
Well, first up, let's talk speed and efficiency.
If you've managed a large network,
you know how much of a chore genes can be with PowerShell,
you can automate the heavy lifting.
So no more clicking through multiple screens,
just surround a command and you're done,
then there's automation and scripting.
Now this is the game changer.
You can script out your regular tasks here need to add a range of D script.
It need to regularly purge stale records, automate it.
I mean, it's all about doing more with less.
And finally,
we've got precision and control when you work manually
or even with the Gooey based tools, you're prone to errors with PowerShell.
You specifically know exactly what you want.
You run the command and the computer does the risks when to roll back.
Well,
PowerShell scripts can easily be undone as they are
done as we journey through the module.
What can you expect?
Well, first of all, we'll dive into DS record management.
We'll look at the importance of different types of DN records like a,
a AAA, the I PV six stuff MX and more,
you'll learn how to manage these efficiently with
PowerShell saving you hours in the long run.
Next, we'll focus on Klein I DNS resolution.
We'll examine how queries are resolved,
what happens when they fail and how you can
troubleshoot issues using PowerShell.
This is critical for ensuring a smooth user experience and
we'll venture into DNS zones and forwarders.
You'll understand the concept of DS zones,
how to set them up and manage them through PowerShell.
We'll also dive into forwarders which are essential for the
efficient query resolutions across the network.
And then finally, we'll end up with everyone's favorite topic,
troubleshooting Ds all while using some PowerShell trickery.
Now that we've covered the theory,
let's jump into a live demo to see PowerShell in action.
So we've got three main tasks ahead.
First, we'll be fetching all DNS records.
We'll use the G DNS server resource record caille to pull up
all records from a specified DNS zone.
And secondly, we'll move to filtering specific records.
Once we have our list, we'll filter out the specific records we need.
This could be something like an A or MX record for a particular zone.
And finally, we'll wrap up with DNS server status.
We're going to show you how to fetch server stats and test the
DNS server to make sure the health is OK.
This way you can keep tabs on your DNS server without breaking a sweat.
I'm here on my srv one server remote into with PowerShell remoting.
It's currently my active directory,
domain controller and DNS server for my domain.
So first up, let's tackle DNS records.
Let's first check on the entire zone of records.
Running G DNS server resource record is the equivalent of opening up
your DNS manager and checking each entry manually.
But hey, where's sys admits?
We automate here.
Get D NSS server resource record is your go to Kalle for finding
DNS records a multitude of different ways.
But hold on.
What if you're only interested in a specific record type?
Well, say maybe a records using the RR type parameter,
filters out everything and shows you only the A records or maybe you'd
like to find records with a particular host name.
Here.
We're applying a different filter filtering on the record name.
Now continue on maybe you have different records pointing to the same IP
address the objects that get DNS server resource record returns has an
object with that data in it called record data.
The record data property contains what the record is pointing to.
In this case, a records point to IP addresses.
Now, if I'd query cname record, you'd see the alias here instead of the IP.
Now knowing this,
you can narrow it down by piping the results to where object and
specifying the IP address you like to filter on.
As you can see the G DNS server resource record.
Kamille has a lot of options and as you should for all Kamal,
lets you can check out the help content and just
scrolling through this massive help content.
You can see if you can think it up.
The Kamala has a way for you to find the records you're looking for.
All right.
So moving on from records, let's talk about the DNS server itself.
If you ever need a quick overview of its configuration,
it's as simple as running, get DNS server.
You can see that this command just outputs the
entirety of a DNS server in a raw format.
I found this command lit to be good for those times when you can't figure out
the right DNS command lett to use to get what you need.
It's a rudimentary way to inspect the DNS server settings.
Alright.
So, and finally, to ensure the DNS server is serving as it should,
you can check his status with test DNS server and test the DNS
server does have a mandatory parameter for IP address even if
you're running it on the DNS server itself.
So my DNS server is 10 004, put that in there and let's see what happens.
All right, it looks like it is successful.
So it looks like it does do a few different tests,
it can do TCP, which is not normally the default.
So it didn't do that,
but it did try ad P query for AD N server and it was successful.
So according to this test, it looks like it's good.
Now,
you can even test various aspects too like checking if a particular zone exists.
But you can see that this nonsense zone clearly is not shown by the result.
So you can see that the result is non authoritative for zone,
which means it's probably on some other data server somewhere.
This test cannot figure it out.
But if you put in a accurate zone name, then you can see the result of success.
That means the zone is hosted on this DNS server and test DNS server has a
few more parameters too to check the status of DNS server.
So I encourage you to check out the help content on that command too.
So quick recap, we dove into how to fetch DNS server records,
filter out specifics and we peeked into a DNS servers health.
This demo should give you a good foundation for managing DNS server.
