Could not retrieve backup settings for primary ID in log shipping

Hi,

I am doing log shipping between two amazon ec2 instances running windows server 2008 R2.

The sql server version is Sql server 2008 R2 standard edition

Both the instances are in the same domain and i can access the shared folders between the intances.

The sql server service account, agent service account are all running under domain account.

When i activate log shipping (with stand by mode restore in secondary server), the inital backup gets restored on the secondary.

After that the backup operation is getting failed and i get the following error message.

* Error: Could not retrieve backup settings for primary ID 'xxxxxx-xxxx-xxxx-xxxx-4d772cd7337e'.(Microsoft.SqlServer.Management.LogShipping) *

* Error: Failed to connect to server IP-0A7653F2.(Microsoft.SqlServer.ConnectionInfo) *

****** Error: A network-related or instance-specific error occurred while establishing a connection to SQL Server.********

The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)(.Net SqlClient Data Provider) * ----- END OF TRANSACTION LOG BACKUP -----**

Please help me on this..

Thanks,

Sarathy
