    Unanswered: Problem while connecting through Control Center

    since morning i am facing Problem while connecting through Control Center
    from my client m/c to any of the servers.
    However through command window i can easily connect/attach to a instance.

    the nodes are present on clients m/c

    SQL22223N The instance "T0" does not exist on host "Tiger".
    Explanation:

    The DB2 Administration Server on host "<hostname>" failed to
    execute a request because the instance "<instance-name>" provided
    in the request does not exist on the host.

    incorrect target instance name
    edit the instance settings and verify that the target instance name is correct

    Directory entry type = LOCAL
    Protocol = TCPIP
    Hostname = TIGER
    Service name = 50000
    Remote instance name = T0

    but this is the output of command line mode config
    In cc - is the information correct ? there are 5 nodes defined
    always try : remove db-instance-system and start again with system
    discover instance-discover db
