Have a sql agent job that is trying to loop through a list of servers. I have added the SQL Agent account as a SYSADMIN on each remote Sql Server it's trying to query. Query looks like this.
------------------
SELECT q.*
FROM OPENROWSET('SQLNCLI', 'Server=SQL01;Trusted_Connection=yes;',
'Select.............. ') AS q
------------------
Error Message
Msg 18456, Level 14, State 1, Line 1
Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
Any ideas?

thanks, ERH

Are all of the server startup services starting up with the same login, and what is the level of permissino for this login. We have over 200 servers talking amongst themselves this way. The startup service is a Domain Admin account and a sysadmin on each of the servers. In this configuration, the only issue we have has is when a DNS issue arises.

It's a "too many steps for Windows authentication" problem. (There's a more formal name, but this one's more expressive.)

Natively, Windows can only pass authentication one step, e.g.: client to server, or server to server. It can't pass more than that, e.g.: client to server to another server.

Any time you see that anonymous login error, you're probably looking at this issue.

It can be solved. Look up "kerberos" online. Or use integrated security. Either one works.

different accounts in the same domain group. the domain group is a sysadmin on each server.

thanks, ERH

Oh no, you said "kerberos". :w00t: I was afraid of that when I noticed no authentication was being passed but I was hoping it was something I could do differently in SQL Server to get around it.

Thanks for the feedback guys. Good article. I'll get it figured out.

thanks, ERH

As Gus said, it is a double-hop or multiple-hop issue which means you need to use Kerberos delegation in order to use trusted authentication with OPENROWSET.

Check out the article I linked to in my first post.

Edit: Oops you posted that you were checking that out while I was posting this. Please disregrad.
