Below is a quote from the WindowsITPro magazine.
" If you have just one domain, Microsoft recommends that you make all
the domain controllers (DCs) GC servers so that your network won't incur
any extra space usage or processing. In essence, the infrastructure
Flexible Single Master Operation (FSMO) role still checks the GC for
many operations. By making all DCs GC servers, you can spread the FSMO's
request load to all DCs and prevent one DC from asking another DC for
information that the first DC already has. Although the FSMO can't
typically reside on a GC, you won't encounter any problems as long as
only one domain exists because the FSMO won't need to keep track of any
external domain objects."
