Login failed for user '(null)'.

I have recently been getting the following error message:
Login failed for user '(null)'. Reason: Not associated
with a trusted SQL Server connection.
Is someone trying to hack into my server, or is there
another explanation for this?
Thanks,

(login) to the server using a trusted connection/Windows
NT authentication and you don't have access through your
windows domain account, hence the 'null' ie the user does
not exist as far as SQL Server is concerned.
