If you name a computer and then prestage it, will it change the name?

For prestaging to work in Windows Server 2008, you need to have WDS (Windows Deployment Services) installed. This is a role and can be installed from the Server Manager. Once WDS is installed, it makes a change to Active Directory Users and Computers. Before this change, when you create a computer name, it would not give you the option to set This is a managed computer. You would simply click OK and be done. After the change, you would enter the computers name and click Next. At this point you can provide the GUID for the new computer. You will find the GUID on the computer or on the shipping material. Now the computer is ready for installation utilizing WDS. The name will then be changed to what you set it to.

For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material. I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO. This is a feature that many Group Policy Administrators may not be aware of.

I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers.

The Compare-Object cmdlet will first find items that are diffe
