AX2012 Installation

Bgiri

We have been following the requirements provided by MS for installing AX2012. When we try starting the AOS, the following error is displayed:

"The Microsoft Dynamics AX Application Object Server is running on an operating system that is not supported. The supported operating system versions are Microsoft Windows Server 2008 and Microsoft Windows Server 2008 R2. "

What have we missed ?

Any help is much appreciated.

Thanks
