I am writing a script to automatically set the "Register this connection's addresses in DNS" & "Use this connection's DNS suffix in DNS" in Advanced TCP/IP Settings on a fresh out of the box device.
I've been successful clicking through the Network Settings prior to running the script in order for those settings to be set. I want to avoid doing that at all cost.
This is my code.
Disable-NetAdapterBinding -Name "*" -ComponentID ms_tcpip6
Get-NetAdapter -name "*" | Set-DnsClient -UseSuffixWhenRegistering $True
When I run this code in powershell only the "Register this connection's addresses in DNS" box is checked not the "Use this connection's DNS suffix in DNS" box.
There are a couple ways to do this. I tend to use the WMI method. First thing to do is get all the adapters that are IP Enabled. Once you have this then all you need to do is use the SetDynamicDNSRegistration Method. This method takes two Overloads both are Boolean and map to the two check boxes (Register this connection's addresses in DNS and Use this connection's DNS suffix in DNS). The below example would check the Register this connection's addresses in DNS box and uncheck the Use this connection's DNS suffix in DNS box"
$adapters = Get-WmiObject Win32_NetworkAdapterConfiguration -Filter "IPEnabled = 'True'"
$adapters.SetDynamicDNSRegistration($true,$false)
This example would result in both boxes being checked:
$adapters = Get-WmiObject Win32_NetworkAdapterConfiguration -Filter "IPEnabled = 'True'"
$adapters.SetDynamicDNSRegistration($true,$true)
I have encountered the same issue.
When setting 'Use this connection's DNS suffix' through the Set-DNSClient cmdlet it appears to run successfully. Running the Get-DNSClient cmdlet shows the the setting being correctly adjusted but the related registry key is not created nor is the GUI updated.
Key - HKLM:\System\CurrentControlSet\Services\TCPIP\Paramters\Interfaces\
Property - RegisterAdapterName
Adapter - IPV4 Properties - Advanced - DNS
During testing I have noticed that after the key is created, either through the WMI code above, REGEDIT or the GUI, the PowerShell cmdlets do correctly amend the registry key/gui.
I have resorted to using code similar to the example provided by DaSmokeDog to force the creation of the registry keys for a given adapter then return to using the simple PowerShell cmdlets afterwards.
Not ideal having to work this way but my (limited) testing shows it working.

I'd like to programmatically create a new Network Profile (in addtion to those listed under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles). Then I'd like to programmatically assign a particular network adapter to it (e.g., vEthernet (WSL)), and set the profile to Private network mode to follow the firewall rules, similar to what we can do for Wi-Fi networks. Is there a Windows or PowerShell API to help with that?
Eventually, the goal is to access Windows network from WSL2 Linux without tweaking the Windows Firewall settings manually.
More context for the question, including some things I've tried so far.
Currently, my solution is to call New-NetFirewallRule -DisplayName "WSL" -Direction Inbound -InterfaceAlias "vEthernet (WSL)" manually each time I need access the Windows host network from WSL2.
Personally, I would avoid P/Invoke if possible - it's usually the most fiddly approach.
I suggest using netsh and parsing the text. Netsh is using the Win32 API under the hood, so that changes your problem from P/Invoke to regex (which I think is usually an easier tool to use).
This may be a useful pointer for the netsh invocation. The salient bits:
netsh lan show profiles
netsh lan export profile folder=PATH_TO_FOLDER interface="INTERFACE_NAME"
netsh lan add profile filename="PATH_AND_FILENAME.xml" interface="INTERFACE_NAME"
IIUC, you don't need a new profile every time, you only need to define that once. From my knowledge of WSL, you get a new IP on every boot, so the issue is assigning that to the one profile that you have created for the task.
If that's correct, then I would export a profile to XML for an existing profile, edit it once manually, then automate applying that XML when you see the WSL adapter.
Not sure if you want to do this interactively, but for full automation, the approach that pops into my mind is to attach a task to the relevant event in Event Viewer. On my box, I didn't spot any obvious event sources for WSL, but the Hyper-V-VmSwitch source looks promising. Here's a sample event:
Log Name: System
Source: Microsoft-Windows-Hyper-V-VmSwitch

Description:
Port D76B3365-5A23-4960-B044-066E05FF3F2D (Friendly Name: A7DB3628-B2A6-4605-AAED-229DB96E064E) successfully created on switch 5EE23C35-0881-4967-A447-FF22139BE1F4 (Friendly Name: WSL).
I've elided over a lot for brevity, but happy to answer follow-up questions.
When I create a vm with defaults, it creates scale set without errors but it I do not seem to be able to RDP to the box using the NAT rule configuration.
New-AzVmss `
-ResourceGroupName $resourceGroup `
-Location "WestUS" `
-VMScaleSetName "tktestScaleSet1" `
-VirtualNetworkName "myVnet1" `
-SubnetName "mySubnet" `
-PublicIpAddressName "tktestvmssPIP1" `
-LoadBalancerName "tktestLoadBalancer1" `
-UpgradePolicyMode "Automatic" `
Even a simple default scaleset creation does not work
$vmssName = <VMSSNAME>
# Create credentials, I am using one way to create credentials, there are others as well.
# Pick one that makes the most sense according to your use case.
$vmPassword = ConvertTo-SecureString <PASSWORD_HERE> -AsPlainText -Force
$vmCred = New-Object System.Management.Automation.PSCredential(<USERNAME_HERE>, $vmPassword)
#Create a VMSS using the default settings
New-AzVmss -Credential $vmCred -VMScaleSetName $vmssName
It also seems to create a nat for 3389 and for 5985. Why is it creating nat for port 5985
This is not the behavior when I create the scaleset from portal for that it does not create the extra NAT rule for 5985 also I am able to RDP.
Is this a bug, or am I configuring it wrong?
It might be expected behavior. I also face the same scenario as you.
By default, that command New-AzVmss with default parameters does not create the health probe but creates a load balancing rule in the Azure portal. In this case, you could add a probe to enable the load balancing rules, then you could RDP to each of the VMSS instances.
You also see the parameters. If no values are specified, ports 3389 and 5985 will be used for Windows VMS, and port 22 will be used for Linux VMs.
From my experiment it looks like a bug with New-AzVmss. After running New-AzVmss I added an NSG to the Network and added inbound rule after that it started to work. It should have created a NSG when running New-AzVmss by default which did not happen but does from the portal.
-SecurityGroupName
The name of the network security group to apply to this Scale Set. If no value is provided, a default network security group with the
same name as the Scale Set will be created and applied to the Scale
Set.
I'm trying to set a new IP-Address by using a powershell script. I use this command:
New-NetIPAddress -InterfaceAlias $interfaceName -IPAddress $_.IPAddress -AddressFamily IPv4 -PrefixLength $maskLegth
However, on a disconnected interface i get this error:
New-NetIPAddress : Inconsistent parameters PolicyStore PersistentStore and Dhcp Enabled
But when i set the -PolicyStore to ActiveStore, the script will run without errors:
New-NetIPAddress -InterfaceAlias $interfaceName -IPAddress $_.IPAddress -AddressFamily IPv4 -PrefixLength $maskLegth -PolicyStore ActiveStore
I'm not quite sure what this property does, since after restart the settings still are in place. Are there any drawbacks here? Or why does this error even come up?
New-NetIPAddress : Inconsistent parameters PolicyStore PersistentStore and Dhcp Enabled
PersistentStore is separate from ActiveStore, and there is also separate GPO store.
These stores are firewall and network configurations.
ActiveStore contains configuration for this computer.
GPO store is configuration from local group policy.
Active store is curentlly active configuration, and includes both GPO and Persistent store.
Problem you are getting is because Persistent store is set to DHCP and you are configuring static address, which makes not sense.
first disable DHCP in active store and then set IP for interface.
For information about these stores and how to set them see:

I am fairly new to PowerShell so please forgive me if the question looks stupid.
I am trying to configure VPN Connections using PowerShell. With the help of PowerShell ISE, I have no trouble creating a VPN connection and configuring VPN specifics. However I also need to set the DNS server of this VPN to 8.8.8.8, a task of which none of the cmdlets in VpnClient module is capable. I figured that all the settings in "Networking" tab is not accessed by VpnClient module so I tried DnsClient, NetAdapter,NetTCPIP and NetConnection, but the commands in these module all need a parameter called either Name or InterfaceAlias.
I successfully changed the DNS Configuration of my Ethernet Adapter by Set-DnsClientServerAddress -InterfaceAlias Ethernet -ServerAddresses 8.8.8.8,8.8.4.4. However, if I give my vpn name to -InterfaceAlias option then PowerShell gives out an error, saying it cannot find such InterfaceAlias.
I listed all interfaces on my Windows but there's no sign of any vpn connection.
All helps are appreciated, thank you!
Thanks to #DavidBrabant, it seems that it is a bug that Microsoft has not fixed since Windows Vista. I then followed one of the solutions on that kb article: using .Net Class.
The result is still the same as before: no sign of any vpn connection. My input and output look like this:
PS C:\WINDOWS\system32> [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces().NetworkInterfaceType
Wireless80211
Wireless80211
Ethernet
Loopback
Tunnel
Tunnel
I haven't tried the second resolution which is "Use the GetAdaptersAddresses API" because I don't know how. Anyone knows? Or did I miss something from the .Net framework?
Since I can't comment and/or +1 anything because of switching to new account. I want to mention that above Antonio's solution works just fine. You have to use common sense and understand things a little more. I will elaborate on Antonio's message. Understand that the people who are answering you are either coding professionals or IT professionals. So they answer in assumption you are one as well. Please do not -1 anything if you haven't tried it and don't understand it. ASK they will help you and explain more if needed.
Set-DnsClientServerAddress -InterfaceAlias Corporate -ServerAddresses 8.8.8.8
Let's break this down. So what is this saying?
Set-DnsClientServerAddress
This is assuming you're already connected to the VPN. as Antonio actually mentioned.
you have to connect to the VPN first
Ok now that we have the understanding that this command through powershell assumes we're connected to the VPN (Only 1 by the way not more than 1).
Let's tackle the rest of the command.
-InterfaceAlias Corporate
Ok so those who code undestand that -InterfaceAlias is a Parameter to the Set-DnsClientServerAddress command. Then following that parameter you have attributes. Now that attribute can either be TEXT (aka a String) or a boolean value (aka $True or $False). So in this case he is saying that his vpn is called Corporate. Now with most Windows stuff. Windows will accept strings un quoted if it's all 1 word. However if your VPN Name has a space in it then it will not accept it. you would have to encapsulate your string with quotes. for example.
-InterfaceAlias "My VPN"
So in this case you need to know what your VPN Name is. If you don't know what your VPN Name is, please go to the following location.
Control Panel -> Netwok and Sharing Center -> Change Adapter Settings (left hand side) -> net find your VPN Adapter.
Alright so the last bit.
-ServerAddresses 8.8.8.8
So this ServerAddresses property is already strictly data typed to an IP address or multiple IP addreseses. So in this case you would need to know the DNS Server you wish to request DNS resolution from and replace it (8.8.8.8 = Google outside DNS server). So for example
-ServerAddresses 10.1.10.254
Now this will set the DNS server to be 10.1.10.254 for this VPN Adapter.
Kill the VPN and then start it up again. Open a command prompt and type the following
ipconfig/all
This will show you all your current adapters. For your VPN adapter it should show your updated DNS. If you still can't resolve DNS names it possibly has to do with your Type of DNS server and you will have to probably specify a DNS suffix manually as well. See the following article for more details.

Hope this helped. Sometimes us Senior IT guys just don't have the time to type it all out for business owners and/or new to the trade IT personnel.
-Grafix
To be able to change the interface DNS of a windows VPN you have to connect to the VPN first then use the PS command
Set-DnsClientServerAddress -InterfaceAlias Corporate -ServerAddresses 8.8.8.8
I did it and after that I was able to join the windows 10 to the domain; also first you have to create the VPN using the PS command
Add-VpnConnection -Name "My VPN" -ServerAddress "x.x.x.x" -TunnelType Pptp -EncryptionLevel Required -AuthenticationMethod MSChapv2 -AllUserConnection -RememberCredential -PassThru
I have several network connections that are connected to different networks.
and I want to make sure that a certain network connection is at the top of the list.
so I want to programmatically script changes to the binding order of network adapters for a windows(win 2008 server and win 2003 server)
Is it any way to change the binding order programmatically?just use wmi, netsh, vbscript, edit regstry or other script or command line tools.
I found edit registry registry HKLM\system\currentcontrolset\services\TCPIP\linkage\ -> bind value,
is a way on windows 2008 server.
use "netstat -rn" can found binding order is changed. but the on the networking advenced UI(ncpa.cpl)
the order is not changed.
and looks it not working on windows 2003 server.
Is any one have idea How to change the binding order of network adapters using commandline?
Thanks
This looks to be what you are after:

Alternatively, you could easily script a batch file that disables the primary adapter so that the adapter you want to be primary takes over. Then re-enable the original one again.
Example:
#echo off
netsh interface set interface "Local Area Connection" DISABLED
:: do something here on the secondary connection
netsh interface set interface "Local Area Connection" ENABLED
