Let's not start the great distro debate again! Suffice it to say that
most distros will work as long as they satisfy your ISV and hardware

File server? Sure, Samba is a breeze, not sure if the performance
scaling is there. NFS works, I guess. Windows comes with a client for
it. Authentication? Again, no problem.
I don't mean to be a snob, but this is basic stuff. I'm guessing you're
requirements are more esoteric so please try to be more specific about

If you look back in the archives of this ML, you'll find a thread from
when Microsoft released their compute cluster product. It covers quite
effectively the positives and negatives of Windows in HPC. Start with
this posting by Jon Forrest.
Do you have an application which can only be run on Windows?

Having as much homogeneity in your cluster as possible will help you
administer it increasingly as a single resource. As Mark said, it's
easier to debug a single set of problems. It's also easier in terms of
infrastructure to maintain a minimal set of images for your clients.
Perhaps you meant something different?
