Hi,

We have 2 windows 2003 DC's (500 users). The FSMo roles are shared as
follows, is this ok?

DC2 - Domain Naming Operations Master
DC1 - RID
DC1 - PDC
DC1 - Infrastructure
DC1 - Schema Master

Thanks in advance for your time.

Is this a single domain forest? Then your choice is actually not that
relevant - although you might want to separate PDC Emulator and RID Master
for performance reasons. You might want to also keep domain naming and
schema masters on the same DC (this is typically done to ensure that both
roles are tightly control - this probably is not that critical in your
case)...
Designate both DCs as Global Catalog...

When I have 2 DC's in a single domain, I split the roles as follows:

DC1: Schema Master, Domain Naming Master
DC2: PDC Emulator, RID Master, Infrastructure Master

See this KB article for best practices, including single domains with 2
DC's:

http://support.microsoft.com/kb/223346

This also explains why you can have the GC on both DC's.

Hello Gonzo,

In a single forest domain you can have them all on one DC or split them,
it doesn't matter. Make all DCs Global catalog server in a single forest
domain. For other recommendations see also the document provided from Richard.

Best regards

Hi
Check the server with more hardware resources and you can place them all in
that DC.

I hope that the information above helps you.
Have a Nice day.
