As of Audit Purpose or Standard Organization Policy, we need to deploy legal notice logon banner message/warning of usage logon message in domain computers.
To do it automatically, we can use logon script/group policy.
Since group policy is easy to mange, I'd like to show you how to do it.
Open group policy management console, go to group policy objects, right click on it and select new to create new GPO as below. (You can create and link directly on the OU that you wish to deploy GPO but I create it separately to show clearly.)
Right click on newly created GPO and select edit to make changes.
Go go Computer Configuration>Windows Settings>Security Settings>Security Options> and find Interactive logon: Message tesxt for users ... . Enable and define the message that you wish to show as logon message.
Find Interactive logon: Message title for users attempting... and Define the message title for your logon message.
After that, link newly created GPO with the OU that you wish to display logon banner.
If you want your GPO immediately, just force update Group Policy via command line or else just wait to refresh the policy automatically by default timer.
Below is the sample logon banner message.
I used the Windows Server 2008 R2 Standard for this demonstration.
Have a good time.
(Be knowledgeable,pass it on then)
