On a Windows 2000 native domain that does not have a "Pre-Windows 2000 Compatible Access Group," and where the MSSQLServer service is run under the local system account, if a job is owned by a Microsoft Windows NT authenticated user, the following error message might occur when the job is run from a local Windows NT administrator or after being scheduled. Reviewing the job history displays the following error message:
The job failed. Unable to determine if the owner (domain\username) of job testjob has server access (reason: Could not obtain information about Windows NT group/user 'domain\username'. [SQLSTATE 42000] (Error 8198)).
Reviewing the SQLAgent errorlog shows an additional error message:
 SQLServer Error: 8198, Could not obtain information about Windows NT group/user 'domain\username'. [SQLSTATE 42000] (ConnIsLoginSysAdmin)
The extended stored procedure xp_logininfo 'domain\username' is being called which returns this error message:
Server: Msg 8198, Level 16, State 8, Procedure xp_logininfo, Line 58 Could not obtain information about Windows NT group/user 'domain\username'.
To work around this problem either:
Change the job owner to a standard SQL Server user or system administrator (sa).
Upgrade to Microsoft Windows 2000 and add the Pre-Windows 2000 Compatible Access Group. Next, add the Everyone group to the Pre-Windows 2000 Compatible Access Group.

By design, Windows 2000 security changes now prevent access to resources that legacy applications (such as SQL Server 7.0) once could successfully access (for example, in Windows NT 4.0).
