This will work.

Import-CSV c:\serverlist.txt| ForEach-Object {.\Set-DNSIP -Name $_ -NetworkName Ethernet -DnsIPs '192.168.33.5','192.168.33.6'}

You will need to have to have the list of Nic names.

How can I use this with a list of servers from a text or csv file.
Something like this:

ForEach-Object {.\Set-DNSIP -Name (Get-Content C:\ServerList.txt) -NetworkName Ethernet -DnsIPs '192.168.33.5','192.168.33.6'}

So far it works great for (1) server name in the text or csv but not for multiple.

This script does not go into the subfolders. Can you provide the script for downloading subfolders and files therein as well?

Thanks

"Here I am creating second self signed certificate but using parameter -Signer which specifies a Certifcate object with which this cmdlet signs the new certificate."
Created certificate is not self-signed. It is signed by specified "Certificate object". Although of course Microsoft called it wrong as usually.
