Error while connecting to external SQL table using BCS identity in SharePoint 2010

Hi all,

I am working on SharePoint Foundation 2010. I have a stand alone setup. Now I am trying to connect to a SQL table in another server. I have used SharePoint Designer to connect using BCS. I have selected "BCS Identity" for authenticating with SQL in the external content type. then I created a list with this external content type.

I get the following error upon opening the external list.

Login failed for user 'INYKGW\sp_farm'.

I am confused. how do I solve this error.

any help is greatly appreciated.

Thanks.
