hi Jo-Anne,
Yes it is another sharepoint production server i used feature.xml file it contains following connection string <Property
Key="ContactsUdcxCxnString" Value="Provider=SQLOLEDB;Data
Source=servername ;Initial Catalog=dbname;Persist Security
Info=True;Integrated Security=SSPI"/>
</Properties>
i used windows authentication. This working fine on dev server but gives error (error occurred while accessing data source) on prod sever . i got entry in event viewer login failed for user reason token-based server access validation failed with an infrastructure error.
Thanks
Rakesh
