Here is a more useful description of IBM's support for 2003. It indicates that it is supported but you need to read note 2 and the readme before attempting installation.

The following site references Windows 2003 being a supported OS: http://www-306.ibm.com/software/integration/websphere/mqplatforms/ but the following technical fact sheet does not mention Windows 2003: http://www-306.ibm.com/software/integration/wmq/v53/g325-1986-00.pdf So does IBM support Windows 2003?
