IIS7, Exchange, and 32-bit apps
I have a beefy but overworked development box I use both to host personal email and to develop web applications. I have only recently plunged into the Exchange 2007 (and therefore 64-bit) world of server OSes, and I have a question that is founded on several assumptions, any one of which might well be completely wrong: Assumptions: - IIS (6) can run in either 32-bit or 64-bit mode, but not both simultaneously - Exchange 2007 requires that IIS run in 64-bit mode for its web client access interface (i.e. OWA) - There is no practical way to get something like Coldfusion or PHP to run on IIS6 in native 64-bit mode short of installing a second web server alongside IIS (when this server has enough to do already...) Question: Does Win2008/IIS7 change this picture at all? Can it run both 64-bit and 32-bit apps simultaneously? If so, will it also make my breakfast for me? Cause that's about the only thing this server won't be doing if it will.

You will be able to run 32 bit appson a 64 bit Windows Server just like you can do in Windows Server 2003. Exchange 2007 requires 64 Bit for every role. PHP - try the FastCGI, http://blogs.iis.net/iisnews/archive/2007/1/31/1599359.aspx A good place for IIS questions in http://forums.iis.net/where there are great forums and experts. Brjann

for what it's worth... Exchange 2007 actually does run on 32-bit, although this isabsolutely no deployment config for production environments. Since you're only running a dev box, you're good to go. I'mcurious howColdfusion 8 runs on Win2008... anyone experienced in this?
