If you have reached this page in hopes to find an answer whether Windows Server 2008 R2 has a 32bit addition available, you have definitely come to the right place. Unfortunately, the answer may not appeal you.
The fact is that Windows Server 2008 R2 is NOT available in a 32 bit edition. Windows Server 2008 R2 is only available for x64 and Itanium 2 processors.
However, that shouldn't be a "show-stopper" for you. According to Microsoft, "Windows Server 2008 R2 builds on the award-winning foundation of Windows Server 2008, expanding existing technology and adding
new features to enable organizations to increase the reliability and flexibility of their server infrastructures. New virtualization tools, Web resources, management enhancements, and exciting Windows 7 integration help save time,
reduce costs, and provide a platform for a dynamic and efficiently managed data center. Powerful tools such as Internet Information Services (IIS) version 7.5, updated Server Manager and Hyper-V platforms and Windows
PowerShell version 2.0 combine to give customers greater control, increased efficiency, and the ability to react to front-line business needs faster than ever before." I tend to agree.
