This allows a Global Catalog Domain Controller to give information about other domains in the forest much faster to the client. Global Catalog servers have information about their own domain and a subset of often used information from all domains in the forest. Remember do not place the Infrastructure Master FSMO role on a server with Global Catalog enabled, unless ALL Domain Controllers is Global Catalog enabled!

In Windows 2008 Active Directory all Domain Controllers are by default Global Catalog servers, personally I would recommend using the same configuration in most Active Directory Setups, unless special needs and loads with multiple domains and quite a few Domain Controllers exist. If more domains exist in the forest, place the domain roles on a server in theese domains like Domain Controller #2 Global Catalog configuration. Place the two forest roles on this server. Recommended Best Practice setup of FSMO roles. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. It is also important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. If you only have one domain controller (not recommended), there is nothing to do since all roles must be on this server, but if you have multiple servers you should move some of theese roles on to more servers. But Best Practice dictates to move some of theese Flexible Single Master of Operation (FSMO) roles to seperate servers.

During installation of Active Directory on a Windows Server 2000/2003/2008 all FSMO roles will automatically be installed on the first server.
