Frequently Asked Questions
What is a Client Access License (CAL) for Windows NT 4.0?
A CAL is a legal requirement from Microsoft that grants a user or device the right to access the services and resources of a Windows NT 4.0 server.
Is this CAL compatible with newer versions of Windows Server, such as Windows Server 2019?
No, this specific CAL is designed solely for Windows NT 4.0 and is not compatible with newer versions of Windows Server.
Who typically needs to purchase a Windows NT 4.0 CAL?
Organizations or individuals still operating Windows NT 4.0 servers who need to license additional users or devices to connect to that server.
Does this CAL include the Windows NT 4.0 server software itself?
No, a CAL only grants access rights; the Windows NT 4.0 server software must be obtained separately.
What happens if I use a Windows NT 4.0 server without the proper CALs?
Operating a server without the appropriate CALs is a violation of Microsoft's licensing terms and could lead to legal and compliance issues.
Is it difficult to find support for Windows NT 4.0 environments today?
Support for Windows NT 4.0 is limited due to its age, as it has long passed its end-of-life cycle, making technical assistance scarce.
