I have a network of about 1200 computers. I have two Win 2003 R2 domain controllers running AD, DNS, DHCP and DFS for the redirected start menu folders (low load on DFS)
1. HP DL380 G4, Single Xeon 3.2Ghz, 2GB RAM, Mirrored drive
2. Dell Poweredge 1450, Single Xeon 2.8GHz, 4.5GB RAM
Both are a global catalog
We don't currently use exchange
This is a college environment with 6 lessons changes per day, so at least 6 log ons and log offs per computer. We also have a print system, and intranet which is linked into AD for authentication.
This is a single site environment.
How many DCs should I have? Is 2 sufficient?
