|Message:||Could not obtain information about Windows NT group/user ‘%ls’.|
|A process executed within SQL Server or from the SQL Server Agent, such as the xp_logininfo stored procedure, a scheduled job, or a replication agent, needs to verify the credentials of a Windows-authenticated login. The attempt to retrieve those credentials on the domain failed for an unspecified reason.
One common cause of this error is a manually created domain group with the name “everyone.” This name conflicts with the built-in hidden group of the same name. Other conflicts between objects in a domain can also cause the problem, as can insufficient permissions to retrieve the information about the objects.
There are many other root causes for this error; many of them are described in more detail in Microsoft Knowledge Base article 834124.
