sql server connectivity issue

If I am trying to run service from local machine - I get message as

Login failed for user ''. The user is not associated with truste开发者_如何转开发d SQL Server connection.

whereas, If I run the service from server - it works fine.

I am also able to connect to server from SQL Server - works fine too

Only while debugging I am getting error

Any guess why ?

thanks in advance.

Things to check:

• Is the service on your local machine using a different connection string to your service from the server (check the .config files)

• Is the service on your local machine running under a different user account then the service on the server
