Hi there, At the momento I am installing an Exchange cluster (SCC.) Everything seems to be going well - NICs configured as they should be, communication tested, shared storage on the SAN seemingly working well. Only one wee problem - the setup log of the cluster on the active node is showing the following error, is this to be expected as I am only just creating the cluster, or is it something that should concern me? [MT] Connection to 'CLUSTERNAME' with binding string 'xxx.xxx.xxx.xxx' failed because the RPC is not available. Thanks in advance.
