Help Needed On SQLServer , Error 18456

Hi All,

I have tried accessing a remote database in one of by stored procs using linked servers and also using OpenDataSource method.
In both the cases , I am getting login failed error.

Following is the stored proc :

CREATE PROCEDURE TEST AS

SELECT *
FROM OPENDATASOURCE(
'SQLOLEDB',
'Data Source=blrkec3432s;User ID=xyz;Password=xyz').LMC.dbo.STATE
GO


It works fine if the userid is 'sa'

Could anyone please tell me the reason for this.

Thanks,
Shanthi
