When an object on one domain controller references an object that is not on that domain controller, it represents that reference as a record containing the GUID, the SID (for references to security principals), and the distinguished name of the object being referenced. If the referenced object moves, its GUID does not change, its SID changes if the move is cross-domain, and its distinguished name always changes.
The infrastructure master for a domain periodically examines the references, within its replica of the directory data, to objects not held on that domain controller. It queries a Global Catalog server for current information about the distinguished name and SID of each referenced object. If this information has changed, the infrastructure master makes the change in its local replica and also replicates the new values to other domain controllers within the domain.
If the infrastructure master runs on a Global Catalog server it will never update anything, because it does not contain any references to objects that it does not hold. That is because a Global Catalog server holds a partial replica of every object in the forest.

Can someone tell me what exactly the problems I might see if I had 2
Domain's and in one of them the Infrastructure Master role was on the GC
with the other DC's in that Domain not also being a GC? This assumes the
first Domain is setup correctly.
So:
Parent.com
DC1 - 5 FSMO roles and GC
DC2 - GC
Child.Parent.com
DC3 - 3 FSMO roles and GC
DC4 - *not* a GC
If I understand correctly, the INF Master's job is to inform other Domain's
of changes to objects in its own Domain. If so, then in the above scenario,
DC3 will fail to inform DC1 of changes to objects in Child...? Just what
kind of changes would it fail to pass along?
