    for "Metadata Cleanup" (there is a very good article on the main site.

    Printers / shares will need to be re-created and scripts edited to re-link them to clients
    DHCP scopes can be re-created

          You are best to do a proper metadata cleanup:
          http://www.petri.com/delete_failed_dcs_from_ad.htm

          Can you describe your site setup -- I presume from above, the failed DC was in a different site and it is the only one?
          Assuming there is a site to site VPN, probably best to use router as primary DNS server and HO DC as secondary until you get a replacement DC up

                  If the router provides DNS, consider suggestion above (primary DNS router, secondary HO Dc) as an interim

                      You will need to upgrade the AD Schema before you can DCPROMO the first 2008R2 box -- normally this is done on the Schema Master FSMO Holder using the correct (32 or 64 bit) version of ADPREP from the 2008R2 media
