Login failed Error: 18456, Severity: 14, State: 11.

The above error says

"
Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. [CLIENT: <IPAddressOfServerA>]
Valid login but server access failure; Default Database access failure. Or Initial database connection failure in connection string.
"

Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. [CLIENT: <IPAddressOfServerB>]
also happens on the other direction.

Where could you affirm the credentials of 'NT AUTHORITY\ANONYMOUS LOGON' account, and that the other server can accept and trust the credentials.

thanks

Under Server Role, NT AUTHORITY\SYSTEM is both 'public' and 'SA' in ServerA. Under 'User Mapping', he does not have any specific database chosen, because he is SA, and also Windows Authentication is what he has under the properties. It is the same in ServerB. ServerA & B are trying to communicate , and both get the same error. Both servers all mixed authentication.

the links talked about the server having linked server. But neither of these servers have any LS..

is the way the login('NT AUTHORITY\SYSTEM') is setup ok?

thanks

just noticed that the error says 'Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. and the login is 'NT AUTHORITY\SYSTEM' which is a windows login, is that my problem?
