Could not obtain information about Windows NT group/user ‘%ls’.

Details
Product: SQL Server
Event ID: 8198
Source: MSSQLServer
Version: 8.0
Component: SQL Engine
Message: Could not obtain information about Windows NT group/user ‘%ls’.
   
Explanation
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.

   
User Action
  • If you can see a domain group called “everyone,” rename or delete that group to avoid a conflict with the hidden group “everyone” that is built in to the domain.
  • Verify trust relationships and firewall settings between any domains involved.
  • Verify that the account used to lookup the domain credentials has sufficient permissions to perform the operation. This account may be the logged-on user or the account used to start either the SQL Server or SQL Server Agent service, depending on the context.
  • Check whether there are any local or global groups, computers, or domain names in any of the local or trusted domains that have the same name as any of the other objects. If there is overlap, rename one or more objects to avoid the duplication.
