Hi I am installing Exchange 2007 SP2 on a new server which will be a CCR cluster. Cluster part has installed/configured correctly, just installing the Active node on Node1, but keeps failing with: "Service 'MSExchangeTransportLogSearch' failed to reach status 'Running' on this server" I've uninstalled and tried again, always fails at this point. Any ideas why? If I try and manually start the service, it times out too. This server will be purely a Mailbox server, nothing to do with Hub Transport, so isn't there a way to just ignore this? Below is copy from installation log: /04/2011 20:16:12] [1] Processing component 'Mailbox System Attendant Dependent Tasks' (Configuring tasks dependent on System Attendant service).

Hi, 1. Please uninstall the exchange server on Node1. 2. First Installed HUB and CAS on another node. 3. After that started installation of Clustered mailbox role on Node1.
