During the installation of Microsoft Exchange Server 2007, the Microsoft Exchange Server Analyzer Tool performs the following operations:

  • Determines whether the cluster name is longer than 15 characters.

  • Determines whether the cluster network name matches the DNS name.

If Exchange Analyzer determines that the Exchange cluster name is longer than 15 characters or if the cluster network name does not match the DNS name, Exchange Analyzer generates the following error message:

Current cluster's name is more than 15 characters, and this will cause setup to fail. Please change the cluster's name and restart setup. Current cluster's name: ClusterName
