While i am trying to execute the steps mentioned in section "Joining the
Windows Server to the Domain"



1. invoked dcpromo.exe

2. select advanced mode installation

3. Select Existing forest

   Add a domain to an existing domain



   Getting the below error ..



   The RPC server is unavailable



   Active Directory Domain Services Installation Wizard : The wizard cannot
gain access to the list of domains in the forest.



   This condition may be caused by a DNS lookup problem. For information
