As new Operating Systems (OS) become available, support for older operating systems become redundant. This has sadly become the case for Microsoft Windows Server 2003 since the 14th July 2015.
What does this mean for me?
If you are unfortunate enough to still be on Microsoft Windows Server 2003, this means that there will no longer be new security patches, fixes, etc available from Microsoft. This makes the operating system vulnerable to attacks and bugs.
Should I stop using it immediately?
Upgrading from Microsoft Windows Server 2003 should not be a task taken lightly. Although users can continue using the operating system, it would be recommended to upgrade to an operating system in support (in my opinion, the latest available).
What else do I need to be aware of?
The operating system may be used to host server applications such as licencing utilities for CAD packages. It is important to ensure that the software versions of such utilities are compatible with newer operating systems, e.g. Microsoft Windows Server 2012 R2. This could be overcome by upgrading the software itself but if this is not possible, another solution must be sought. In this case, please speak to your software vendor for advice.
