Can't connect to DAC connection through SSMS

  • Hello - 

    I'm trying to connect to the DAC through SSMS 17.8.1 using the ADMIN:INSTANCENAME syntax, but I keep getting the following error:
    Dedicated Administrator connections are not supported via SSMS as it establishes multiple connections by design.

    Is this the new functionality in SSMS 17, or do I have another problem?  Thanks in advance.

  • Not a new functionality. As it says, SSMS default "connect to server" will open multiple connections(Object explorer). The trick is to connect using query pane or thru "Database Engine Query". The below blog post explains it in detail...

  • There are times you'll get this but if you look at your current query, it can be connected with the DAC, but you've gotten an error from the Object Explorer or another object.

  • Thank you for your respnses
