Ok so I have a script that connects to a mssql db and i need to run as a service which I have already accomplished but when I run it as a service it overrides my credentials that I have put in when i connect to the db with the ad computer account.

It runs perfect when i run it on its own and not as a service.

My Connection String is:


'DRIVER={SQL Server};SERVER=MyServer;DATABASE=MyDB;UID=DOMAIN\myusername;PWD=A;Trusted_Connection=True'

The Error is:


Error: ('28000', "[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'DOMAIN\COMPUTERNAME')

Any Advice?

    The following connection string will use Windows authentication, using the account running the service to authenticate with the database. Change the service account to one that has database access:

    'DRIVER={SQL Server};SERVER=SERVERNAME;DATABASE=DBName;Trusted_Connection=yes'

    To change service account:

    • Start -> Run -> services.msc
    • Right-click service -> Properties
    • Log On tab
    • OK/Apply to save changes
