  • Hello,

    i have no idea about BMC portal, what is this kind of application doing?

    RPC errors often belong to firewalls that are not open for AD related ports or DNS is not configured correct for the domain internal DNS servers ONLY. http://technet.microsoft.com/en-us/library/dd772723(WS.10).aspx

  • As suggested check the firewall ports required for the app to work (I think RPC uses TC 135). Make sure the application is fully updated. Make sure you don't have an IPsec policy configured.

    Is the application located in the local domain or DMZ?

  • The message you posted is related to RPC issue.This could occur due dns misconfig on the server or necessary port not open for AD communication,n/w connectivity issue,etc.

    On the DC check the dns setting,run dcdiag /q and repadmin /replsum to check for any errors and post the same.

    Also, disable local windows firewall service, by default it is enabled in vista/windows 2008 and above. Check the network connectivity and latency.
    Disable Windows Firewall:http://technet.microsoft.com/en-us/library/cc766337(WS.10).aspx

    It can also be caused by antivirus software with many of them sporting a new feature called "network traffic protection," which can efffectively block necessary AD traffic.

    Ensure the following on DC:
    1. Each DC / DNS server points to its private IP address as primary DNS server and other remote/local DNS servers as secondary in TCP/IP properties.
    2. Each DC has just one IP address and single network adapter is enabled.
    3. Contact your ISP and get valid DNS IPs from them and add it in to the forwarders, Do not set public DNS server in TCP/IP setting of DC.
    4. Once you are done, run "ipconfig /flushdns & ipconfig /registerdns", restart DNS and NETLOGON service each DC.
    Do not put private DNS IP addresses in forwarder list.
    5.Assigning static IP address to DC if IP address is assigned by DHCP server to DC.It is strongly not recommended.
