  • Hi,
    I was trying to set mirror without using domain accounts. So I had Sql server service running on both principal and mirror server(no witness)under administrator account which I had with the same password. Telnet on 5022 on both servers worked fine, but I was getting 1418 error. In that case the problem for sure was with the permissions. I found that I couldn’t login to one of the servers using windows authentication and user: administrator. I created that login and gave it sysadmin server role. I loged in as administrator in sql studio and after that and mirror was established.

  • Solution: If your using local accounts
    1. Change Service accounts for MSSQL server from Local System to Administrator Account ( Principalserver\Administrator and Mirrorserver\Administrator)
    2. Restart the Mirroring

  • I could fix it by doing the following:
    1- using Domain user has admin right to run both of SQL Service and SQL Agent in (Principal, Witness, and Mirroring) Servers.
    2- Restart all serivices
    3- Drop Current openned EndPoints and recreat them once again using TSQL or SSMS wizard itself.
    4-Check the Encryption box for all servers (Principal, Witness, Mirror)

    Hope this help

    Hi, everyone,
    After several months searching i today solved the problem. If above all are ok, i mean –
    1) All end points for principal, mirror, witness server instance are listening properly and status is started for all instances.
    2) Same domain account has been created for all instances and sysadmin permission has been given.

    Then last thing to do is :

    3) add NT AUTHORITY\NETWORK SERVICE login account for both mirror, principal and witness server instances and make sure it has sysadmin server role permission. That’s it. This solves my problem. I hope this will solve the problems of many.

    Thank you. :)

  • I was having exactly same problem and tried all the steps mentioned above. But this dint work, Since i was using test environment, Added another instance on the same server and still found the same issue for error 1418 for tcp. Looked at the services and my server service and Browser service were using NTAuthority network servcie account, changed these to Domain user ( i added the user as sysadmin) and it started working. Hope you will find this helpful.
