Infrastructure role - how intensive?

Hi there,

We've got our domain. It's got 3 sites (as set up in sites and services). We
have 4 domain controllers as follows:

1. Site A - DC_A
2. Site B - DC_B
3. Site C - DC_C and DC_D (A virtual server)

Now - A, B and C are GCs because they are each in their own site. C holds
the majority of the roles.
I know the infrastrcuture role should not be held on a GC so i've got it on
D.
Is this correct?

How intensive is this role? I'd rather not stress a virtual machine you
see -rather it just be there as the backup.

Thanks,

Hello David,

Doesn't matter in a single forest domain, yours sounds like this. See also

Also i would make all DC's GC server.

Hi,
Sorry should have added that information.

The domain i'm talking about is the root forest domain. Below that we have a
child domain (not used as much).
We also have some NT domains trusted as well.

Thanks,

Hi

-Do you have exchange? If yes, or if you've any other App that needs a GC
make sure that you have a GC close to the Exchange server.

-The IM shouldn't be placed on a GC when NOT ALL DCs for that Domain are
GCs. Make All DCs = GCs and you shouldn't have a problem with that,
especially true if your FFL (Forest functional Level) is 2003 or later.

I hope that the information above helps you.

But with it being virtual is there an issue doing this? Is it intensive?

Thanks,

Normal/NonGCs that are DCs already have all the information that a GC has,
assuming single domain/forest. So making it a GC doesn't "hurt" them.

No the IM is not a processor intensive role.

I am missing why you're worried about the IM though. Is this a single domain
forst? If so all your DCs (all four of them) should be marked GCs. The IM
doesn't do anything in a single domain forest either way.

For the IM role, yes, it warns you. It still is a warning that you need to
*evaluate* against your environment to see if it applies. However it does
not prevent the move

The FSMO placement "issue" with GCs only applies to the IM FSMO in a certain
scenario. If you have multiple domains, the IM of a *certain* domain cannot
sit on a GC IF there exists ANOTHER DC in the same domain that is not a GC.
I'm saying certain domain, so this needs to be evaluated for every domain in
the forest

If you have a single domain, make sure ALL DCs are GCs! Just do it
