The RPC server is unavailable (0x800706BA)


  • I've searched and searched and search, only got until sept to virtualize this server and migrate it to SBS 2008.  lucky me considering i just graduated from college. Anyway here are the details.

    Small Business Server 2003 with SP2
    Using SCVMM 2008 R2 on Windows Server 2008 box with Hyper-V
    I am using the convert physical computer section
    I fill out the IP, domain admin account and password (I want to try a local admin account but for some reason I cannot find the local admin username or password anywhere)
    I have successfully converted a Server2003 box as a test before doing the SBS.
    When I goto "Scan System" i get this error and cannot find anything on google or technet that helps me.

    VMM is unable to complete the request. The connection to the agent <IP ADDRESS> was lost.

    Ensure that the computer <IP ADDRESS> exists on the network, WMI service and the agent are installed and running and that a firewall is not blocking HTTP and WMI traffic.

    Details: The RPC server is unavailable (0x800706BA)

    I can ping from both machines successfully
    This is our only DC on the network which also does our exchange.

    Anyone got anything I can try out?

  • Error says RPC service is unavailable. Remote Procedure call can be blocked by the firewall. On the command prompt type winrm quickconfig and that will create a firewall exception. IF this doesnt work try to check your dns settings. Can you ping the FQDN of the target server ?

  • I tried the winrm quickconfig command and sbs2003 doesnt recognize this command.
    I can also ping the FQDN of the target server.

  • then you can try shutting down the firewall and make sure Remote procedure call service is running. You can check it throught services.msc

  • p2v uses WMI for source machine communication.
    please check firewall and wmi settings on the physical machine to convert

  • it looks like i was able to scan the system.  i entered the computer name instead of the domain name.  I will be attempting the virtualization tongiht after hours since it is our DC and need to do an offline

  • Windows Firewall is off and still getting the RPC server is unavailable. (Exception from HRESULT: 0x800706BA).  This happened after ocsp1 & ocsp2 certs were updated they no longer see each other.  They are in same subnet and can ping each other with ip or dns name.  I can't Add Array Member due to this RPC server is unavailable.
