Bamboo does not start after updating windows credentials

[Jorge Guerra]

After updating the windows credentials in our bamboo server, the service fails to start even though it is listed by windows as running, when acceding via `localhost:80805` it returns ERR_CONNECTION_REFUSED.

The `<bamboo-home>/logs/atlasian.bamboo-log` file shows this error after running `<bamboo-folder>/bin/start-bamboo.bat`
