Could not contact the SSO server RRS feed

  • Question

  • Hello All,

    we tried to move BizTalk SQL servers to new server, everything went smoothly but when we try to refresh BizTalk group in admin console we are getting following error.

    TITLE: BizTalk Server Administration
    ------------------------------

    Could not contact the SSO server ''. Check that SSO is configured and that the SSO service is running on that server. (WinMgmt)

    For help, click: http://go.microsoft.com/fwlink/?LinkId=47400&ProdName=Microsoft+BizTalk+Server+2010&ProdVer=3.9.469.0&EvtSrc=BTSAdminMsg&EvtID=10767

    ------------------------------
    ADDITIONAL INFORMATION:

     (RPC: 0x800706D9: There are no more endpoints available from the endpoint mapper.)

    ------------------------------
    BUTTONS:

    OK

    Can some one tell me what permissions do we need in SSO servers.

    Thanks,

  • Hi Cahandresh,

    Check the Enterprise Single SignON Service from services.msc and make sure that it has proper credentials and is running.

  • Hello Rajesh,

    Please make sure that "Remote Procedure Call (RPC)" windows service and "Enterprise Single Sign-On" service is running? 
    Also check "Enterprise Single Sign-On" user credentials, i.e. using which userid the windows service is running, could you please check the userid & password for that user and Make sure that the user is part of the SSO Administrators windows group?

  • Hi Mandar,

    SSO server is running remotely and we don't have access to that server..

  • Hi Rachit,

    I'm getting following error for RPC

    RPC Access denied. See the event log (on computer 'Server Name') for more details. 

     and we are not part of SSO admin group

    Thanks

  • Hi Rajesh,

    You need to specify a valid SSO administrator account for the ENTSSO Service and restart the service from Services Control Manager (SCM) snap-in. Also follow the steps in How to Set the SSO Server to make sure you are connected to the correct SSO Server and make sure the SSO Service is enabled and running in the SSO Server to which you are connecting.

  • Hi chandresh,

    Log On to the remote server and check there in the services.msc

    Also if the SSO is not running your Host Instances (all the in process) will stop. So check if all the Host Instances are stopped and you would also get the warning and error on the Biztalk application regarding this.

    Also can you calarify and we are not part of SSO admin group

    Who is we here?? By we do you mean the users logging on to the server or the user who are supposed to be the users in the Biztalk environment???

  • Hi, Since the SSO server is remote wrt to the BizTalk Admin console , it connects to the remote SSO Service through RPC endpoint mapper ( the SSO service port number is allocated dynamically by the endpoint mapper).

    The error "There are no more endpoints available from the endpoint mapper" seems to indicate that the allowed range of dynamic RPC ports have exhausted or the firewall rules to the server block the port range.

    1) Make sure that the "RPC Endpoint mapper" service is running on the SSO server.

    2)  Make sure there are for in bound firewall rules on the SSO server are not block Rpc EMM port 135 and the dynamically allocated port range, https://technet.microsoft.com/en-us/library/2007.07.howitworks.aspx

    http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/error-1753-there-are-no-more-endpoints-available/de6f9381-fea6-4bee-b646-b06b81f75d19

    3) Try rebooting the SSO server , this might help if it is in fact RPC EMM dynamically allocated ports within the default range have exhausted.


    4) Also check that the SSO service is actually running https://social.msdn.microsoft.com/Forums/en-US/e92dca5a-f318-4304-b223-b812f3abea06/biztalk-sso-configuration-problem-there-are-no-more-endpoints-available-from-the-endpoint-mapper?forum=biztalkgeneral
