I see in the sql server logs, lot of messages every minute
Message
Login failed for user 'Server name'. [CLIENT: xxx.xx.xxx.xx](IP Address of the machine)
It follows with
Message
Error: 18456, Severity: 14, State: 16.
The server on which I am getting these messages is the dev server and the failing user is the production server.
How can I resolve this?
Thanks,
Sushant

State 16 means that the user does not have permission to log into their target database.
Usually happens when the user does not have permission to their default database.
Check the default database for this user and make sure they have access or change the default database

You should look at Logon triggers. This was introduced in SQL 2005 SP2 if I am not mistaken.

Do you have any linked servers created? To me sounds like credentials are wrong!
