I've been tasked with building a Remote Desktop Services server. My machine is an HP DL380 with dual Xenon 3.6 GHz processors, 10GB RAM, 6x 73GB SCSI drives, Gig ethernet card, etc. It will have Office, Visual Studio, SQL Server management tools, Quickbooks, and a few other programs installed. It will be serving 35 employees, but realistically no more than five at a time.
What are some best practices or guidelines I should follow as far as RAIDing and partitioning the drives, setting up the OS, and hardening the box go?
Edit: this is my first time building a Windows server. I have had some Linux experience in the past.
