SQL Server and Active Directory Trusts RRS feed

  • Question

  • Hello,

    In order to stop using SQL users on our environment we decided to use Windows users. So this is the full picture.

    We have AD A and AD B. AD B has the databases (SQL Server 2016) and trusts users from AD A to login.

    I have set up windows logins from AD A in the databases in AD B.

    The problem is the connectivity is really slow. I do not think this is a bottleneck issue but rather some bad configuration.

    To see what happens on the server side I set up an audit and asked a user to login with windows authentication.

    I noticed that there are 3-4 login failed whenever he logs in. Also these appear when he tries to do something. 

    Any tips on improving performance? 

    Thank you,

  • Hello Cathy,

    I have read the article, thank you.

    Here is the error i'm receiving :

    Statement Network error code 0x2746 occurred while establishing a connection; the connection has been closed. This may have been caused by client or server login timeout expiration. Time spent during login: total 4508 ms, enqueued 0 ms, network writes 0 ms, network reads 4508 ms, establishing SSL 0 ms, network reads during SSL 0 ms, network writes during SSL 0 ms, secure calls during SSL 0 ms, enqueued during SSL 0 ms, negotiating SSPI 0 ms, network reads during SSPI 0 ms, network writes during SSPI 0 ms, secure calls during SSPI 0 ms, enqueued during SSPI 0 ms, validating login 0 ms, including user-defined login processing 0 ms. [CLIENT: IP]
    Additional Information <action_info xmlns=""><pooled_connection>0</pooled_connection><error>0x000045a6</error><state>105</state><address>IP</address></action_info>

    I noticed that this only happens in SSMS. Azure Data Studio and sqlcmd seem to work much better.

    Seems to be a DNS issue so i added the server ip to the hosts file.

    The problem that I have now is that i wouldn't want to add the ip's manually or via gpo.

    Any suggestions?

    Thank you,
