client/server handshaking failed(26)

 

My Exchange GRT Backup is getting failed with the following error code.

client/server handshaking failed(26)

All the ports are open from Master/Media to Exchange Mailbox and we are able to telnet on both directions, but still getting same error.

Find the job detail logs are attached.

 

 

  • PLEASE believe me when I tell you that NBU is CASE SENSITIVE.

    kacst-dag001 != KACTST-DAG001

    Are you running all connection test and ping commands on master as well as media server?

  •  

    I Change the name to Small lettters and now backup is working fine.

        Best to start a new discussion where you explain your situation.
  • We can see in one of your tags that you are using NBU 7.5.

    Can you confirm that this version is also installed on all DAG members?

    We see status 58 in Job Details:

    Cannot connect to KACST-DAG001
    Info (pid=0) done. status: 58: can't connect to client
    

    We normally see this when there is a firewall issue or when client is unable to resolve server's IP address to hostname that appears in SERVER list.

    Is KACTST-DAG001 a physical or virtual hostname?

    Please ensure that you have bpcd log folder on all DAG members, then do the follwing from master and media server:

    bptestbpcd -client KACTST-DAG001 -debug -verbose.

    Please post output of betestbpcd command(s) as well as bpcd log on all DAG members.

    What happens if you ping KACTST-DAG001?

    Check on master and media server.

    PLEASE also answer rest of questions in my previous post?

    I do not ask questions to be difficult, but it order to assist, we need as much information as possible.
