SQL Logshipping 2005 - Load Delay Period Problem

Hi,

We are implementing Log shipping feature of SQL Server 2005.
We are facing some issues when the RESTORE job is restoring the TRN
files on the Secondary server.

The error we are facing is as follows: "Skipping log backup file since
load delay period has not expired".

During the setup, we did specify the Delay Restoring Backups value to
0 (zero), but still it gives the above stated error message during
execution of RESTORE job.

The primary server has Enterprise Edition of SQL Server 2005 (SP2).
The secondary server has both, Enterprise Edition of SQL Server 2005
(SP2) and SQL Server 2000 (SP4) instance.

Please let us know if there is any link/solution for the above issue.
