I am currently installing an exchange 2007 CCR. The client access and hub transport server installed with no problems. The Server I installed the Active Clustered Mailbox role also installed with no problems, but when installing the Passive Clustered Mailbox role on the passive node I get the following error during the install:
Service 'MSExchangeADTopology' failed to start. Check the event log for possible reasons for the service start failures.
The event log error;
The Microsoft Exchange Active Directory Topology Service service terminated with specific error 2147943798 (0x80070576) Event id - 7024
Any ideas why I'm getting this? Thanks.
