Could not obtain information about Windows NT group/user
I have a Windows 2012 Server running SharePoint 2010 using an SQL Server Express locally installed. Unfortunately my logs are currently flooding with message "An exception occurred while enqueueing a message in the target queue. Error: 15404, State: 19. Could not obtain information about Windows NT group/user 'DOMAIN\user', error code 0x5." It can be 20 such messages every second!
(...and the 'DOMAIN\user' happens to be my personal account.)
Are there a job running that has missing rights? "Qoute from https://serverfault.com/questions/277551/mssqlserver-exception-occurred-while-enqueueing-a-message-in-the-target-queue-e "Try to changing the owner of the jobs to the sa account, on the properties of the job." If I'm correct the express version of SQL server cannot run jobs? Or is there someone/something that wants access to our AD? Why do that account wants to obtain information about my account 20 times every second?
I do find lot's of blogs and hints about this task, but I just dont understand the solutions. One says "To repair this, login as one of the SA accounts and grant SA access for the account that needs it." But what account needs sa access?
Answer
Hopefully this will help someone else:
In my case, sa was not the owner of the DB, I was. When I tried to execute CLR configuration that required sa privileges, I got this error.
The solution:
USE MyDB
GO
ALTER DATABASE MyDB set TRUSTWORTHY ON;
GO
EXEC dbo.sp_changedbowner @loginame = N'sa', @map = false
GO
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'clr enabled', 1;
GO
RECONFIGURE;
GO
I used help from the db team at work and this post to find the answer. Hope it helps.
