I’ve tried to create routing group connectors between my two Exchange 2010 SP1 Hub Transport / Client Access servers (EX2010H1 and EX2010H2) and the two clustered Exchange 2003 Hub Transport / Mailbox servers (EXCH1 and EXCH2).
I ran the Exchange Shell command:
New-RoutingGroupConnector -name ex2010H1-svrexch1 -SourceTransportServers ex2010H1.domainname.org.uk -TargetTransportServers svrexch1.domainname.org.uk -Bidirectional $true
This was successful creating routing group connectors between EX2010H1 / EX2010H2 and the 2003 server EXCH1.
When I try to run the command to create connectors between EX2010H1 / EX2010H2 and the 2003 server EXCH2 it shows the following error:
Active Directory operation failed on SVRDC01.domainname.org.uk. 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: 000020B5: AtrErr: DSID-03152804, #1:
0: 000020B5: DSID-03152804, problem 1005 (CONSTRAINT_ATT_TYPE), data 0, Att 482330e2 (msExchTargetBridgeheadServers
+ CategoryInfo : NotSpecified: (0:Int32) [New-RoutingGroupConnector], ADConstraintViolationException
+ FullyQualifiedErrorId : 854B6AE9,Microsoft.Exchange.Management.SystemConfigurationTasks.NewRoutingGroupConnector
I've tried pointing the Exchange servers to different DCs but this hasn't helped.
