I have 2 sites and 3 DC's at each site. My boss things we should go down to 1 DC per site. Each site has < 100 users per site. I have: 2 Exchange Servers at site #1 {will consolidate to 1 clustered server later in life}. 1 Exchange Server at site #2 The 3rd DC at each site was put online to repair a bad DC at each site. It was free to leave it so I did. Site #1 the repair is completed. Site #2 the repair is not due to the complexity of how the DC is tied to things {DHCP, DNS, File Sharing, Print Server - Get the picture?}. - I've removed printing - Eventually I want to demote this DC and run on the other 2 DC's. I'm looking for some good facts {links} to back up my claim that I need at least 2 per site. Exchange is a DC hog in itself. Anyone have any links to that effect? Thanks in advance. MAJ
Hi MAJ, You may want to refer to this KB for information: 875427 Global catalog server placement and ratios in an Exchange 2000 Server http://support.microsoft.com/?id=875427 It is preferable to have at least two GCs in each Active Directory site that contains an Exchange server for scalability and fault tolerance.
