cannot add AD Domain Service. "RPC Server is unavailable"

-

hi, unable promote windows 2008 r2 member server dc.  after running dcpromo, following results:

  operation failed because:    active directory domain services not create ntds settings object for active directory domain controller cn=ntds settings, cn=dc1,cn=servers,cn=default-first-site-name,cn=sites,cn=configuration,dc=domain,dc=com on remote ad dc dc2.domain.com. ensure provided network credentials have sufficient permissions.    "the rpc server unavailable."

the ipconfig/all results existing dc (dc2):

windows ip configuration

the ipconfig/all results from the member server need promote as dc is:

i tried turning off firewall on both servers and made sure rpcss running on dc2. using credentials of domain administrator.

any suggestions?

thanks!

you can use static ports ad replication if required.  but make sure configure on dcs.  do have firewall between dcs? make sure following ports open:

this issue sounds firewall/ports related issue.
