How can I update my DNS server IP addresses on my Windows 8 client?
According to Brian Wilhite, Charlotte Windows PowerShell user group member: Luckily, there is a Windows PowerShell cmdlet that does this very thing. The Set-DnsClientServerAddress is just the ticket to perform this task. It’s in the DnsClient module. We’ll also use the InterfaceAlias and ServerAddresses parameters.
Set-DnsClientServerAddress -InterfaceAlias Wi-Fi -ServerAddresses 10.1.1.10, 10.1.1.11
