Set Network Adapter Profile to Private

For Windows 2016, it does not seems like there is a clear way to do it from GUI, so i have to do it using the cmdlet.

First list down all the network adapter, important thing is the InterfaceIndex.

PS C:\Users\Administrator> Get-NetConnectionProfile Name : Unidentified network InterfaceAlias : SLOT 4 Port 2 InterfaceIndex : 19 NetworkCategory : Public IPv4Connectivity : NoTraffic IPv6Connectivity : NoTraffic Name : Unidentified network InterfaceAlias : NIC2 InterfaceIndex : 13 NetworkCategory : Public IPv4Connectivity : NoTraffic IPv6Connectivity : NoTraffic

Then you can execute the cmdlet below to set the adapter profile to private. In this example, i am setting SLOT 4 Port 2 which has the InterfaceIndex of 19

 

PS C:\Users\Administrator> Set-NetConnectionProfile -InterfaceIndex 19 -NetworkCategory Private

Create local user using powershell script

 First of all, prepare the user list as below and save it as users.csv file

username, user, description, password user1, user1, this is user1, password1 user2, user2, this is user2, password2

Create a powershell script with the following code

$localUsers = Import-csv C:\scripts\users.csv foreach( $user in $localUsers) { $Secure_String_Pwd = ConvertTo-SecureString $user.password -AsPlainText -Force New-LocalUser $user.username -Password $Secure_String_Pwd -FullName $user.user -Description $user.description Set-LocalUser -Name $user.username -PasswordNeverExpires:$true Add-LocalGroupMember -Group "Administrators" -Member $user.username }

The scripts will first need to convert the password string from the csv file into a secureString. This is necessary for New-LocalUser cmdlet. After that, the script will set PasswordNeverExpires option as well as add those user into Administrators group.

I am using this script for my test setup which need a lot of dummy users. For production environment, you can actually create random password instead of specifying password in the users.csv file and set the "-ChangePasswordAtLogon $true" option. And obviously, you can also change the User group to "Users" group instead of "Administrators" group.
