    The easiest solution may be to (quickly) rebuild the first DC. And make sure
    to not re-use the name of the dead DC. While doing that, you can force the
    FSMO roles to the working DC. There are technet articles on this, I don't
    have the links on me but a google search will quickly find them.

    You can dcpromo the "new" DC. And now you're back up and running. If you
    want to, you can transfer the FSMO roles back. There is also a process to
    remove the dead DC. Again, there are very helpful Technet articles that you
    can search for.

    I hope this helps you out, and best of luck!

    I have had no trouble with re-using the name but using a new one is
    certainly
    ok.

    You will need to (eventually) do "NTDSUtil metadata cleanup" to remove the
    Old/Dead DC in that case.

    NTDSUtil ROLES will also allow you to seize those roles to the working
    DC.
    Also make sure you have a GC -- in a single domain forest every DC should
    be a GC.

    And DNS as well (likely you first DC was [one of] your DNS Server) and
    WINS Server if you have more than one subnet.

    Remove entries from the clients/DHCP that refer to the old DNS (and WINS)
    Server.

  4. make the DC:
    * a GC --> use sites and services
    * seize all FSMO roles to the live DC that previously were hosted by the DC
    that crashed
    --> see: http://blogs.dirteam.com/blogs/jorge/archive/2006/01/05/373.aspx &
    http://blogs.dirteam.com/blogs/jorge/archive/2005/11/19/111.aspx
    * DNS server (make sure to point clients to this server also)

    clean AD metadata of DC that crashed
    --> http://blogs.dirteam.com/blogs/jorge/archive/2005/12/03/213.aspx

    reinstall the crashed DC with the same apps, roles, etc
    make it a GC --> use sites and services

    transfer FSMO roles back
    --> see: http://blogs.dirteam.com/blogs/jorge/archive/2006/01/05/373.aspx &

    make backups!
