Hi,
solution for this issue is give remote login user id and password in linked server properties.
1.Add linked server using sp_addlinkedserver 'server name'
2.Right Click -->Properties --> Security -->Add --> Give Remote User & password for Local Login
3.Below that u can find a text 'For a login not defined in the list above,Connection will' with four radio button options
Select last option - Be made using this security context Remote Login with password.
This simple solution worked for me.
Thanks
Deepika
