How do I fix error 18456 in SQL Server 2012?.Solutions To Microsoft SQL Server Error 18456.Can’t connect to SQL Server Login failed for user SA?.What I must mention is that the DB's were not created new and was a restore from another server. The user is a member of the administrators group and a user on the server with every role assigned to it with access to every database and also DB owner on all.

We have checked network conectivity to active directory and found no issue what I do know is that state 16 is when the user does not have access to the database. This "small" problem has given nightmares for the last 3 or so months. The second is that only the symptoms of the problem is treated but the original problen remains. The first is that if it was a security issue the re-try would have also failed. I have a couple of concerns regarding the above issues. I have never seen something like this not even in my consulting days. This has worked and the job now executes still with the first failure but the re-try works. The job has run for 2 days without any errors.Īnother anomaly that has me stunned: I enabled a re-try on the particular step to re-try once after a minute. Subsequently I scheduled the package that fails within its own job to run every 10 minutes to try and catch the error and resolve it.

If you have a look at the time the errors occurred in the Job history and view the SQL server logs the same message is shown. Unable to connect to SQL Server 'servername'. The step failed.įor the T-SQL statement executing the proc The error within the job engine history isĮxecuted as user: domain\username. This is the error that SQL server has in the server logs This has been resolved by not connecting to the DB in question but connecting to master DB instead and changing the DB programmaticaly using the "use DB_Name" command in the statement plane then executing the proc. The second issue I have was on step 13 that was an T-SQL statement that connected to a DB and executed a proc.

If I log onto the server using terminal services and connect to the server using the windows credential, the same credentials that start the SQL server and all relevant services and re-execute from step 5 the package executes without any hassels. The user that executes the T-SQL statements and the SSIS packages is the same user and this user has been given every security permission I could find within SQL 2005 (I might not have found all the permissions)įirstly on only one of the SSIS packages I get an error message. The T-SQL statements use the SQL server agent user. In the job there are different staps ranging from SSIS packages to t-SQL statementsĪll SSIS packages are configures to use Windows authentication/integrated security. I have a job that executes every morning at 8:00
