The SQL Agent was configured to run using Contoso\sqlservice.

In login properties, this account also has "system administrator" rights.

Executed log reader agent using a command prompt, received similar error..

C:\Program Files\Microsoft SQL Server\110\COM>logread.exe -Publisher [SQLONE] -PublisherDB [AdventureWorks2012] -Distributor [SQLONE] -DistributorSecurityMode 1  -Continuous

I received Similar error as above

Problem: - This issue arises sometimes when database owner remains blank, then this issue comes.

For RCA you can refer this link:-

Resolution:-


This Error usually comes when owner of Published database remains blank..

Hence to resolve this issue..
 

ALTER Authorization on DATABASE::[<dbname>] to [sa] --Make  sure sa is enabled.

or

sp_changedbowner 'Contoso\sqlservice'
