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?

Change the owner to sa. Here are the steps I took to solve this issue:

1. Right-Click on the database and select properties

2. Click on Files under the Select a page

3. Under the Owner, but just below the Database Name on the right-hand pane, select sa as the owner.

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 the error too.

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.

In my case the owner of the database was a domain account Domain\Me.

The error message was

Error: 15404, State: 19. Could not obtain information about Windows NT group/user 'Domain\MyAccount'

The problem was that the database didn't know what to do with the domain account - so the logical thing to do was to use a local account instead.

I tried changing the owner of the database, but things still wouldn't work correctly.

In the end I dropped and recreated the entire database MAKING SURE THAT THE OWNER WAS SA

I also set the Broker to Enabled in the settings

Thing started magically working after this

I had this error from a scheduled job in sql Server Agent, in my case, just after I changed the hostname of the Windows Server. I had also ran sp_dropserver and sp_addserver. My database was owned by "sa", not a Windows user.

I could login into SQL as the Windows user NEWHOSTNAME\username (I guess after a hostname change, the SID doesn't change, that's why it worked automatically?).

However, in SQL, in Security/Logins node, I had SQL logins defined as OLDHOSTNAME\username. I connected to SQL using "sa" instead of Windows Integrated, dropped the old logins, and create new ones with NEWHOSTNAME\username.

The error disappeared.

to do a bulk update for all databases, run this script and then execute its output:

 SELECT 'ALTER AUTHORIZATION ON DATABASE::' + QUOTENAME(name) + ' TO [sa];' 
 from sys.databases
     where name not in ('master', 'model', 'tempdb')
