  • 1.  MSRPC connection issue

    Posted Sun June 27, 2021 06:23 AM

    i am trying to integrate a server using MSRPC but am having issue with it, In the console it is not showing any status. i used the test tool to try and debug it and it gives me

    Remote registry connection failed with STATUS_PIPE_NOT_AVAILABLE

    which i am not able to figure out what it is related to.

    The user is in the Event Log Readers group, used the same on other server and it works fine

    both services are enabled

    • Remote Procedure Call (RPC)
    • RPC Endpoint Mapper

    Firewall is not blocking anything

    tried restarting the services and turning off the firewall but its still showing the same issue and i am stumped, below entire log

    It looks to be access/permission issue.

    Make sure that the user "qradar" is part of "Even Log Readers" and "Backup Operators" groups on the Windows server...

    After this is done, restart ecs-ec-ingress service
