- Every AD forest has a server which indexes all the objects in the forest. This is known as the Global Catalog server.
- Each domain needs at least 1 GC server, can have more for redundancy. This is so it can find objects in other domains.
- Any DC can be GC.
- By default all DCs will be GCs. GCs take up disk space and bandwidth, but both are plentiful.
- Microsoft Exchange requires GC server to run.
- Allow logins via UPN eg. [email protected], which may be on same domain.
- GC servers should be deployed at sites with poor WAN links or filtered connections.
