I am replacing and old 2003 File Server getting old and running out of disk space. My network is all 2003 Server and XP. I am configuring a new server and am wondering if going with Server 2008 is a good choice for this right now. I have installed and played with 2008 through its beta steps but have not put one into production. I am looking for someone to help me answer the question of 2003 or 2008. The only function it will perform, at least for awhile will be File Server. Seems safe to me, but looking for experienced opinions.
