I am really confused where to start from I would like to populate just two fields in network adapter setting. those two fields are preferred DNS and alternate DNS. The ip will be allocated dynamically using DHCP. At the moment I fill the two fields manually but i want a powershell script to do this. I searched over internet but its really confusing. Can some one please help
you could try with wmi :
$card=Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "IPEnabled=true"
$card.EnableStatic('192.168.1.2','255.255.255.0')
$carte.SetGateways('192.168.1.1')
$carte.SetDNSServerSearchOrder(#('192.168.1.10','10.10.1.8'))
I'm not sure if Powershell itself has such function but you could use netsh from Powershell like this:
netsh interface ip set dns "<connection name>" static 1.2.3.4 primary
netsh interface ip add dns "<connection name>" 1.2.3.5
You may also use WMI to adjust LAN interface settings but I think this is way easier.
Take a look at

he shows how to create scripts for static and dynamic, shouldn't be too dificult to adapt to your needs.

IPSec policies and associated IP filter lists are used just for IP filtering (no encryption).
I believe all IPSec filter lists and policies are domain wide, GPOs only handle which single IPSec policy to apply?
I've used whatever google-fu I have on how to enumerate the many IPSec IP filters we have on domain/GPO and cannot get a meaningful result.
Can get Windows Firewall with Advanced Security results successfully using Get-NetFirewallRule and Show-NetFirewallRule.
Tried these commands Get-NetIPsecRule and Show-NetIPsecRule
Using their -PolicyStore argument such as:
# Always results in empty even if the GPO in question has a policy assigned.
# However am looking for all IP filters specified (which are domain wide as far as I can see)
Get-NetIPSecRule -PolicyStore domain.fqdn.com\GPO_Friendly_Name
# Fails as no GPO is specified
Get-NetIPSecRule -PolicyStore domain.fqdn.com
netsh commands so far have been on local machine or a remote machine which doesn't work for this situation.
Please feel to correct my above assumptions if they're wrong.
Any help would be appreciated! Thank you!
I'll have some computers with 8 network adapters, but only one is configured with the routed VLAN.
To identify it, I wrote a little powershell script that is a loop that assigns the IP address, test the Gateway connectivity until it founds the correct interface.
But when I try to release the IP address using enableDHCP method it will never clears the IP Address nor the Gateway.
I already tried releaseDhcpLease, for individual or for ALL interfaces, but without result ...
I've tried some tricks published here -> https://social.technet.microsoft.com/Forums/ie/en-US/94f0f04a-1669-4276-b529-e68edffd9aff/how-to-remove-default-gateway?forum=winserverpowershell
But none works..
the only effective method for to release the IP configuration was using "netsh command", for example:
netsh int ipv4 -name='Ethernet 3' addr=172.22.33.123 gateway=all
How can I do the same using Powershell + WMI commands? I may invoke "netsh", but script becomes little more complex than I desire.

I write script that need to be used in different active directory forests.
In one forest I am able to use simple computer names that are the same as the computer samaccountname value.
mycomputername
In another forest I have to use dnshostnames that are normally shaped like
mycomputername.some.domain.path.com
Is this a forest setting and how can I identify this?
If you want to connect to a remote host by name you must be able to resolve the name (be it a hostname or FQDN) to an IP address. Whether you can resolve a hostname or need an FQDN depends on the search domains that are configured (or not configured) on a computer's network adapter.
In my home network , I have to set IP address and DNS server. In Office network that settings to be removed .
Daily i am doing this activity manually. Though powershell automate so many things ,I am not finding any cmdlet for this in Windows 7.
I am doing the procedure manually . Is there any way to solve this using powershell? Even if batch file is there for it , I can use it
Here is a script that I use for that.
$wmi = Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"
if($wmi.count -eq 1)
{
$wmi.EnableStatic("10.0.0.2", "255.255.255.0")
$wmi.SetGateways("10.0.0.1", 1)
$wmi.SetDNSServerSearchOrder(#("10.0.0.3","10.0.0.4"))
}
An an even better option for most situation (especially home networks) is to use DHCP. If you have a wireless router, It should have that option.
Isn't PowerShell a bit of overkill?
You can use simple NETSH command from command line.
To check config:
netsh interface ip show config
To turn on DHCP:
netsh interface ip set address name="Local Area Connection" source=dhcp
To setup static address:
netsh interface ip set address name="Local Area Connection" source=static addr=192.168.0.100 mask=255.255.255.0 gateway=192.168.0.1
I've seen a few different tutes covering remoting configuration - this one seems better than average - but I'm not clear how I configure for a situation where the workstations are not of the same domain.
I'm using LogMeIn/Hamachi to create a VPN - I'd like an overview of the steps required to allow script execution for these workstations. Specifically, how do I define TrustedHosts so that onle my VPN peers are permitted?
I don't know anything about the LogMeIn\Hamachi VPN network, but I assume that the hostnames are preserved when using it. (it not this may not help!)
If you want to trust a particular machine you use this:
set-item WSMan:\localhost\Client\TrustedHosts -value <Remote-computer-name>
If it's a domain you can use this:
set-item WSMan:\localhost\Client\TrustedHosts -value *.subdomain.domain.com
Check out the about FAQ as well (Get-Help about_Remote_FAQ) - that's where the first came from, the second I've used.
HTH,
