Exchange 2007 Setup Error: Service “MSEXCHANGETransport” failed to reach status ‘running’ on this server
Scenario: Installing Exchange 2007 SP1 on Windows Server 2008 Server, in a new Forest, new Domain deployment. During the HUB Transport Server Role install, the E2K7 install failed with this error:
Hub Transport Role
Failed Error: Service ‘MSExchangeTransport’ failed to reach status ‘Running’ on this server.
After some digging and Google research, it appears the problem stems from IPv6 being disabled on the servers NIC. I had disabled IPv6 when the server was first installed on the network, knowing it was not necessary for my networks’ topology. Evidently Exchange 2007 requires otherwise. Re-enabling IPv6 and booting the server resolved the issue.
