With all servers in the COLO, would RODC be ok at HQ?

For a client we are moving all of their servers offsite.  For their 700 user HQ we'll leave just print servers and DCs.  The client is asking if we could just use Read-only DCs in HQ.  While technically that should work (no Exchange servers will be in that site), I'm not sure how comfortable I am with that.  Maybe it's just fine and I'm being too conservative.

I know that certain functions, such as changing passwords and adding machines to the domain, would be unavailable if the HQ is isolated from the COLO.  I don't see this as much of a problem.  If both of their redundant 1GB fiber links are down and ALL production servers are unreachable, then they have bigger problems than trying to add a workstation to the domain in HQ!

Anybody have any thoughts or experience?

Thanks.

The reason you would put an RODC at a site is security and some other things. 700 users is a bit much for an RODC. You are running at an HQ as well. I wouldn't put an RODC in this type of situation.


Who will be interested in this feature?

RODC is designed primarily to be deployed in remote or branch office environments. Branch offices typically have the following characteristics:

Relatively few users

Poor physical security

Relatively poor network bandwidth to a hub site

Little knowledge of information technology (IT)

Thanks for the sanity check.  That's pretty much exactly what I was thinking.

I've sent an email to the client laying out all the potential cons and the very limited pros.  Hopefully he'll see the light!

Thanks.
