Hi, I am trying to deploy Windows 2008 R2 for my client, they have over 500 staff and want to use 1 server as their DC/DNS. As I understand it seems there is a limitation for Users on each 2008 servers, up to 500 per DC(Based on SID). I would like to ask, is that information right or I could add more than 500 users on one DC? I believe it would be good to add: 1: They do not have any other servers to be used 2: Virtualization might be a possibility ( Currently they consider, bare-metal server installation) Thanks for your responses beforehand
