[Samba] Joining a Windows Server 2008 / 2008 R2 DC to a Samba AD - ISSUE - The RPC server is unavailable

[Arjit Gupta]

Hi ,


We have configured and run SAMBA-4.5 AD DC on Itanium HP UX 11iv3.



We have tried to join the windows server 2008 DC to samba AD with the steps
mentioned in the below link



https://wiki.samba.org/index.php/Joining_a_Windows_Server_
2008_/_2008_R2_DC_to_a_Samba_AD



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
about troubleshooting common DNS lookup problems,

   please see the following Microsoft Web site: http://go.microsoft.com/
