Hello All, Not sure why this is happening and was wondering if you could shed some light on this subject.
We have a Windows 2K3 R2 native single domain with 2 DCs.
Exchange 2003 Ent Ed SP2
DC1 - holds all FRSO roles
DC2 - Global Catalog
Our Exchange 2003 server is set to auto detect the config and GC domain controllers.
Recipient Update Service (Ent Config) - DC2
Recipient Update Service (Domain) - DC1
When we reboot DC1 all clients report a connection lose to the Exchange server if they have Outlook open. They are then prompted to log back on to this server via Outlook once DC1 comes back on line.
Should DC2 take over if DC1 is down so this does not happen? Is it because DC1 holds all FRSO roles?
Event Viewer messages on Exchange server when we reboot DC1:
Process MAD.EXE (PID=2232). All Domain Controller Servers in use are not responding:
LDAP Bind was unsuccessful on directory DC1.fpb.local for distinguished name ''. Directory returned error:[0x51] Server Down. DC=fpb,DC=local

Thanks for all your help in this matter.
