Via SSMS I'm able to connect and navigate the server/db in question. but trying to connect via a logparser script the same credentials fail. I'm trying to execute this from the same box on which the server's running. the username is owner/dbo of the db. The db has mixed mode authentication.

[linebreaks for clarity]
