Global Catalog is Down

My network consists of one domain, two domain controllers that also run dns, one exchange 2003 enterprise sever.  One of my domain controllers is down.  This one also happened to be the global catalog server.  Although users can log onto their workstations their microsoft outlook clients are failing on authentication.  I also checked the services on the exchange server and the exchange server server is not started.  In the event log it states the global catalog server cannot be found.  Can a windows 2003 domain have more than one global catalog server?  If yes, how can i set this up?

Using Active Directory Sites and Services expand the domain controllers and right click on NTDS Settings and put a check in the box to make it a Gloval Catalog.

In a single domain environment I normally make all my DC's Global Catalog servers.

What difference dies the location of the FSMO roles make?

This is of no relevance for Exchange or Active Directory as long as the server that is currently down will be comming back on line.

If it's completely failed then that's a whole other story.

You will need to seize the 5 FSMO roles as per:  http://support.microsoft.com/kb/255504

then you will need to perform a METADATA cleanup as per: http://support.microsoft.com/kb/216498 or if you prefer the Petri version of this then:  http://www.petri.co.il/delete_failed_dcs_from_ad.htm

As I said in my post, if the DC has completely failed them you will need to seize the roles. There is no other option.

It osnot cometely clear if the DC is recoverable or not.

But the question does not say the server has completely failed I was just providing the options since you brought up the FSMO roles.

The power supply failed. It should be fixed within 12 hours. I just want to give users the ability to send/receive email in the meantime.
