Do you mean AD(Active Directory) ? How can I learn how to do it, please ?You need a Windows Server and a Domain.
Then you can install to all connected computers the same updates or configurations...
What do you mean by part of Domain, can you explain it please or give me any site where I can learn it, please.If they are part of domain Powershell would be an easy way to do this, if not you could combine Powershell and psexec.
