I would like some advice on how to best configure a small workgroup (15-25 users) using the best integration methods with what is on hand. Here is the situation: the company already has 3 servers, a PE 2600 (5 yrs old) that runs SBS2003, another Terminal Server box that runs TS and Backup (Windows Server 2003), and lastly a new PE 2900 with no OS. I would like a recommendation for moving forward. The PE 2900 is the newest and I would like it to be the backbone. Here are my questions:
How should my DC, DNS and DHCP be separated and which machines should run what OS?
What is the best configuration for IIS and Exchange (same machine or separate)?
Which box should run SQL and my mail filtering programs?
Ideally I would like your best recommendation and how you would setup this small network for redundancy and performance.
Thank you in advance!
