I took the plunge. I have had the bits for 2008 for a little while and I finally decided to set it up for my TFS environment. Windows Server 2003 is so last year! My buddy ET blogged a few weeks ago on installing TFS on Windows 2008 32 bit. I used his post as a guide, but added a little more detail to some of his steps and updated the overall process for 64 bit. Sadly, the TFS App tier does not run on 64bit Windows and no amount of begging by me would get the product team to send me a patch. *sigh*...
