Run locally or remote. Recently I provisioned new domain controllers as part of a migration from a R2 Active Directory forest to a Active Directory forest. Like the existing R2 domain controllers, the new domain controllers are configured as AD integrated DNS servers and will be the primary and secondary DNS servers used on the internal network. However if you are like a lot of environments, you have Windows servers and maybe even workstations configured with static IP addresses and static DNS servers.
How can you systematically update these configurations? For compatibility, we will be demonstrating using Get-WmiInstance. In our scenario, our old DNS servers were We will be replacing these with The previous section covered the basic updating of the DNS servers locally on a single computer.
However you may have the need to update multiple computers remotely. One approach would be to query your Active Directory to get a list of all computers that have statically assigned IP addresses. We now have a set of computers to process. We will use Invoke-Command to connect via WinRM to the remote computer and execute the previous commands locally on the computer.
We could use the WMI cmdlets directly against the remote computer, but it would require all of the necessary network port access and permissions for using WMI remotely. Connecting using WinRM only requires a single network port to be opened and lets us run all other cmdlets without having to give a lot of thought to remote security and performance over the network. The method described above is intended for maximum compatibility: it will work with Windows Server all the way through Windows Server Note that we specified the InterfaceIndex.
Other interface identification options are InterfaceAlias or you can pass a CimInstance for an interface to the cmdlet. You could use this cmdlet in hybrid with our previous Get-WmiObject query:. For big companies this is likely to fail on older computers — and they are still likely to be around. You are right though, anything older than that and you will have to resort to legacy tool sets. In my use-case I am moving a DC from one environment to another.
I need to be able to apply the changes remotely. Using Infrastructure as code IaC e. Your email address will not be published. Leave this field empty. Name : " -ForegroundColor Yellow.

We have already shown you how you can change your IP address from the command promptwhich required long netsh commands, now we are doing the same thing in PowerShell, without the complexity. Note: The following commands are new in PowerShell v3 and therefore require Windows 8, they also require an administrative command prompt.
While a bit confusing at first, mostly due to the lack of documentation at the moment, it starts to make sense once the geeks shows you how its done. So here it is:.

It looks like I can successfully pull all of the DNS records from a particular zone. What if I need just a particular type of record rather than all records? I spend most of my time managing the A records.
No problem: simply use the RRType parameter and specify an A. One of our server names has changed and I need to be sure its DNS record is updated to reflect that. Changing DNS records is a little convoluted but, with some tenacity, we can still make it happen.

If that were the case, a company might have a CSV file with the server names and IPs those servers now need. This is a little late but I was able to solve Tim's issue.
I had to update each individual item of the collection.It's pretty easy. This whole process will take around a minute to do so. But what if you have to do it on multiple systems and repeat all these steps multiple times.
It will become really tiresome. PowerShell can do this tedious task very easily. PowerShell may sound difficult to use and you may hesitate to work on it but it has several unique features. With PowerShell, you can gather information, change system settings and automate most anything on Windows. It's more powerful than Cmd and offers more flexibility.
Tasks done with PowerShell does not only automated but they also save time.
Change DNS Servers for Computers with Static IP Addresses
All of the above commands are used to view current configurations. To set a new IP address, execute below command. Replace xxx. Up till now, we have configured IP address, subnet mask, and Default-gateway successfully. Now one thing is missing that is DNS server address.

Example 1: Set the DNS server addresses on an interface with a specified index value. Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To get the job results, use the Receive-Job cmdlet. Runs the cmdlet in a remote session or on a remote computer. The default is the current session on the local computer.
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet. Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output. Specifies the maximum number of concurrent operations that can be established to run the cmdlet. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
This parameter must be used with the ServerAddress parameter. The Microsoft. The path after the pound sign provides the namespace and class name for the underlying WMI object.

How to use PowerShell for DNS Records
Or to even add various DNS tasks to automation scripts. Using this cmdlet, you can specify the ZoneName parameter which will list all DNS records in that zone. This behavior highlights one of the advantages of this particular cmdlet over the graphical DNS console. The view gives you all of the records for this zone, regardless of which folder they are in. In the graphical console, it would take quite some time to piece this information together.
Now thin out this list a bit. Taking this one step further, you can also search for records in a different DNS zone and even on different DNS servers. In the example below, we will search for A records in the canada.
In this example below, you need to add a host record for a new printer that you are adding to the network. It will be added to the corp. If it turns out that you need to remove a record, perhaps the printer has been decommissioned, you can use the following code to remove the host record that we just created:.
It is also just as easy to add an IPv6 host record. Of course, these records differ slightly, as they are listed as AAAA records. It's a subtle change, but an important one. Add a record to the corp. A reverse lookup record allows the client to query a DNS server to request the hostname for a supplied IP address.
Change DNS ip addressess remotely on multiple computers
Creating a PTR record is a relatively easy process, but there is one important bit of information you will need to know before you start adding PTR records.
Reverse lookup zones are not created by default. You will need to set up your reverse lookup zone prior to adding records. Fortunately, it is relatively easy to do. In this instance, since you're creating a reverse lookup zone, provide it with the Network ID.
As this record is for the canada. When using this cmdlet, it is important to note a couple of things. Once you have those pieces of information, the code required to create the PTR record is relatively simple, if a bit long:. These records allow you to specify an alias for an existing host record in the zone. This becomes especially useful, for example, if you want to provide your finance users with an address for their web-enabled finance app.
You could create an alias called financeand point it to the web server webapp Once the app is migrated to the new web server with a new hostname, you'd then change the CNAME record to point finance that points to the new host. This way, the users don't have to update their bookmarks. They can continue to access their application using the address finance.
