In this article, we will be discussing how to display interactive logon messages for Windows PCs via GPO. We will be discussing two specific policies and implementing them via the Group Policy Object (GPO) and Windows Registry. They are “The Interactive logon: Message text for users attempting to log on and Interactive logon: Message title for users attempting to log on policy settings” and are closely related. These settings are part of the GPO Security options. Please see The different Windows Logon Types, The logon attempt failed for the remote desktop connection, and What are the merits and demerits of Local System Account and Service Logon Account.
The Security Options contain security policy settings that allow you to configure the behaviour of the local PCs. Please see display logon banners for Windows PCs via Windows Registry.
These policies can also be included in a Group Policy Object and distributed over your organization.Why Enable Interactive logon Messages for Windows Computers
Enabling “Interactive Logon Messages for Windows PCs” involves displaying a legal notice or warning message to users before they log on to a Windows computer.
These messages are often used to communicate vital information, legal or security policies to users. There are several reasons why organizations choose to enable interactive logon messages for Windows and Network devices. But our focus of discussion today is the Windows PC.
- Legal and Compliance Requirements: In some industries, there are legal and compliance requirements that mandate informing users about specific policies, agreements, or legal terms before they log on. Displaying a logon message helps fulfil these requirements and ensures that users are aware of their responsibilities and obligations.
- Security Awareness: Organizations use logon messages to raise security awareness among their employees. This reminds them not to engage in risky online behaviour.
- Announcements and Updates: Important announcements, updates, maintenance schedules, or system changes can be communicated through logon messages. This ensures that users are informed of any upcoming changes or disruptions.
- Unauthorized Access Deterrence: Displaying a warning message can act as a deterrent against unauthorized access attempts. Potential intruders may be discouraged from attempting to log on if they are presented with a clear message indicating that unauthorized access is prohibited.
- Disclaimers and Liability Notices: Organizations often include disclaimers and liability notices in logon messages to protect themselves from legal liability.
These fields can be used to communicate “Emergency Contact Information“, Education and training, Acceptable Use Policies etc.
