Thank you for your post into the forum and sorry that you having problems with SQL Response.
Please right click the SQL Server you cannot connect to and select server properties.
Run the Test Credentials, when the test fails move the mouse cursor over the 'yellow warning triangle' and 'incorrect username password' message. A tooltip type message should appear with further details of the error. What is the tool tip message? Hopefully it will contain further information.
Also a support call has been created for you, the call reference number is F0036656. Can you please send an e-mail to email@example.com
, with the call reference number in the subject field with a copy of the Alert Repository Log file attached?
To locate the Alert Repository Log file, please click on the SQL Response icon in the very top left hand corner of the SQL Response Client immediately above the file menu ->Select the option to 'Copy Alert Repository Log file'.
