Exchange 2007 SP1 Install Error on Windows Server 2008 RC1

This is one "simple" error I come across when installing on Windows Server 2008 RC1.
Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=1976). Topology discovery failed, error 0x80040a02 (DSC_E_NO_SUITABLE_CDC). Look up the Lightweight Directory Access Protocol (LDAP) error code specified in the event description. To do this, use Microsoft Knowledge Base article 218185, "Microsoft LDAP Error Codes." Use the information in that article to learn more about the cause and resolution to this error. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers.
In my case solution was really simple. Between the tests I disabled IPv6 support on network card. I enable it back, re-run setup and everything was fine...
