Resolution
This issue occurs because of a change in SQL Server 2005.
SQL Server 2000 required the following multiple-step restore process: Restore the file or the file group from the full database backup.The database remains in a restoring state. Restore the transaction log or logs from the log backup chain. SQL Server 2005 tries to restore the log files and the data files in a single step. Some third-party snapshot backup utilities do not support the single-step approach.
