Hi all, Let me state upfront that I'm in way over my head right now. However, we're in no rush, and I'm happy to learn. Short of blowing up my server, I have the time to make some mistakes. I want to install SQL Server Express 2008 on my company's server, running SBS 2003 Std R2. We're a small company (<10), and right now using Access for database needs. However, I want something more robust for business as our company grows. I'm writing C# code for bespoke client applications that we will run that will access the database. We will not be data intensive by any stretch. I recognize there is a mix of expertise that I'm missing right now, both on the database admin side AND on the SBS admin side. The first thing I encountered when attempting a 'jump into the water' first go at installation was a warning that it's not recommended that I install SQL Server on a primary domain controller. Immediate red lights for me - clearly not the same as installing on my laptop running XP!! After searching around on the web, I couldn't find a good place to start. I couldn't find the answers to (what I thought were) simple questions, such as: Ok, if I don't install it on a PDC, where do I install it if I've only got the one server? So - 1) any suggestions to whether or not I should install on a primary domain controller? 2) any suggestions as to where I should go to start learning about domain controllers, installing and setting up SQL Express 2008 on my server, etc? Thanks in advance for any help. I'm sure there are folks gasping out there at my naivete, but I've got to start somewhere!! :-) Rob
