Rebooting DC (Exchange related)

Hi

We are running Exchange 2007 SP2. Within the same AD site, we a bunch of GC's (GC1.domain.com, GC2.domain.com, GC3.domain.com).

One of the GC's needs to be rebooted. From what I understand, Exchange only uses on GC at a time. When this GC is rebooted, I want to make sure none of our Exchange servers is using it :)

I have come across this article here:

http://msexchangeguru.com/2010/05/09/hardcoding-domaincontroller-exchange2007/

It gives steps on how to hardcode a GC (and un-hardcore).

Some questions -

1. Does this apply to *all* Exchange server types (CAS, HT, MBX etc)

2. The article states I need to recycle services, does anyone know which one?

3. Is this a recommended way to avoid any problems when I'm about to reboot a GC?

4. I guess if the GC was going to be rebooted out of hours, we could take the hit with Exchange. Am I correct in thinking that once the GC Exchange was looking at was back, Exch would function again as normal?

5. Is there a PowerShell commandlet to find out which GC is Exchange is using, or is Event ID 2080 the only way?

Thanks guys, but what is the time period for DSAccess to automatically choose another GC? During that period, isn't Exchange effectively dead?
I could not find any documentation on this topic but I've actually moved GC from one server to another with no notable failure on exchange's end.

(moved as in added new GC waited for replicaion then removed the old gc)
