The default mapping states that SQL Server uses the user credentials of the local login when connecting to the linked server on behalf of the login. This is equivalent to executing sp_addlinkedsrvlogin with @useself set to true for the linked server, without specifying a local user name. I am getting the following error: Msg 18456, Level 14, State 1, Line 1 Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

Each instance is installed on a http://dba.stackexchange.com/questions/7111/local-login-impersonation-not-working-with-a-linked-server separate machine and both are included in the same domain. I can access Instance A from Machine B and i can access Instance B from Machine A (with both SQLServer Authentication and Windows Authentication)... no problem here. I've created a Linked Server connection from Instance B to Instance A without a problem. I can access all https://social.msdn.microsoft.com/Forums/sqlserver/en-US/7e75b7d7-641f-4519-b5ea-9567985a2cce/linked-server-error-login-failed-for-user-nt-authorityanonymous-logon?forum=sqldatabaseengine my databases from instance A in this linked server. The problem is creating Linked Server from Instance A to Instance B. I get no error creating it, but i can't access any databases from Instance B. I get the following error: Login Failed for user 'NT AUTHORITY\ANONYMOUS LOGON' (Microsoft SQL Server, Error: 18456). I've been reading about this in some forums but no solutions seem to help... Any help please? Thanks in advance for any help, SuperJBJB Friday, February 18, 2011 2:57 PM Reply | Quote Answers 0 Sign in to vote This is most likely caused by the SPN onInstanceB not being set.

Server A is SQL 2005 windows logins only Server B is the same (SQL 2005 windows logins only) Server A runs login failed for windows XP Server B runs Windows Server 2003 Both SQL Server services are running under the same domain account.

The number itself deliberately doesn't tell you much, so crackers can't use it for clues on where their attempts are going wrong. –Tony Hopkinson Jan 4 '14 at 16:10 8 @David if you see a duplicate question in SO, then mark this as such. Just because the answer is easy to come by, doesn't mean it doesn't belong on SO.
