As of July 14th 2015, Windows Server 2003 will no longer be supported by Microsoft. Security patches and updates will not be released, and users will need to migrate prior to the end date to ensure the security of their systems.
Recently Microsoft were alerted to JASBUG (MS15-011), a fifteen year old vulnerability that was discovered by an external source. JASBUG is a critical vulnerability affecting all Windows operating systems, and could allow hackers to remotely hijack machines. A patch to fix the issue was released, but the patch does not work on Windows Server 2003.
As Windows 2003 will no longer be supported, continuing to use the server without security updates puts businesses at risk. Users will have to migrate to a more recent version of Windows Server (such as Windows Server 2012) to ensure optimum security. Migration may take a substantial amount of time, so it is recommended to start migrating to a new server as soon as possible.
