You
cannot
use the
Mail Flow Settings page in Exchange Server
2007 Setup to select a bridgehead server in the existing cluster that is
hosting a legacy Exchange
server. When you select the Exchange Server 2007
server as the Exchange source server and select any legacy Exchange cluster
servers that are running on a Windows 2000 platform as the target server for
the routing group connector
In other words, a
routing group connector should
be created in Exchange Server 2007
during the Exchange Server 2007 Setup. This requires
a computer account to
be add to
the ExchangeLegacyInterop security group for the connected computer in
Active Directory. However, this computer account does not exist
because Windows Server 2000 cluster servers do not have a computer
account in the Active Directory directory service.
Therefore, the computer account cannot be added to the ExchangeLegacyInterop
security group.
In this scenario, you receive the following error
message:
Cannot find computer object in Active Directory
for server 'virtual server name'
If you
manually create the Routing Group Connector by using the
New-RoutingGroupConnector command, you receive the following error message:
New-RoutingGroupConnector : Active Directory operation
failed on <GC Server>.Domain.com. This error is not retriable. Additional
information: The name reference is invalid. This may be caused by replication
latency between Active Directory domain controllers. Active directory response:

If you install Microsoft Windows 2000 Server Service Pack 3 (SP3),
you can create a computer account in Active Directory for the cluster virtual
server. However, this configuration is not supported for Exchange 2000 Server.
Kerberos authentication for the Network Name resource on which
Exchange 2000 Server depends is not supported on a server cluster. Exchange
2000 Server was not tested with the expectation that a cluster virtual server
would support Kerberos authentication. This configuration may not function
correctly.
Future versions of Exchange Server may take advantage of
Kerberos authentication for server clusters.
