A domain login is attempting to connect to a database server that it doesn't have access to. You need to examine the app to see what it's doing, how it's connecting, connection string, the works, and the database server to ensure that the login does exist and does have the correct access.

This can happen when your application cannot contact Domain Controller (DC) server, for instance if client is in one domain and sql server is in another domain and also the trusted link between those domains has been broken or does not exist.

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
