Ive never been quite sure whether my domain has the correct or optimal site configuration. My infrastructure consists of the following:
2003 domain with 2008 DC's
Site1: contain 70% servers has 2 domain controller. Contains all FSMO roles
Site2: Datacenter - no users. Termination of VPN users and main connection for or MPLS networks for WAN
Site3: Germany. 2008DC and Users
Site4: France. 2008 DC and users
Basically when I setup a domain controlelr on another site it will automatically create the site connection to Site2 as that is the closet DC it will find on the MPLS network.
The problem with this it seem to create an extra step as most of our servers are Site1. So it a user changes a password on a remote site (site3) it has to replicate to site 2 before it then replicates to site1. For example this causes lots of problems when logging onto citrix servers in site1.
I have left the default setting within sites and services for replicating once every hour and all connections are automatically generated. Is it best practice to change these?
