Am using the hub-and-spoke model. The hub has 7 DCs with 4 being GCs. The hub connects 30 sites with each site having a DC and a GC.
This a forest with two domains - production and QA domains. we have exchange server at each site. A site has several 4 - 20 branches hanging off it
The Question is; what will the recommended configuration per site with respect to GCs and DCs ?
Any issues make all DC at the (30) sites GCs? what are the pros and cons?
