Question : LDAP bind unsuccessful (Exchange 2003)

We have Exchange 2003 setup on Windows 2003 which is connected to one domain with two domain controllers, all on the same site.

Active Directory is hosted by these two servers with the five domain roles distributed between both servers. “server1” holds the PDC emulator, Domain-Naming master and the Schema, “server2” holds the RID master and Infrastructure master for the domain. “server1” being the first controller in the domain has the Global Catalog.

We've had a problem recently where "server1" has shut down and this affects Exchange which stops working, you cannot log onto the information store.  Exchange has the following in event viewer

Event Type:      Error

Any suggestions as to how I could get around this problem if "server1" goes down ?  I'm new to all the AD stuff  and am looking for a little guidance

Many thanks

Answer : LDAP bind unsuccessful (Exchange 2003)

I think you will have to do that manually , anyway you will need to Promote the new server to a Global Catalog server once the server1 goes down
