To restore the Project Server database, you can use the restore feature of Microsoft SQL Server. To do this, follow these steps:
1. Click Start, click AllPrograms, click Microsoft SQL Server, and then click SQL Server Man-agement Studio.
2. In the Connect to Server dialog, the Server Type should be "Database Engine". Check the Server name and Authentication and make changes if needed, then click the Connect button.
3. Expand SQL Server if needed and then expand Databases.
4. Right-click the database, point to All Tasks, and then click Restore then click Database….
5. From the list of backups, click the backup to restore, and then click OK to start the restore.
6. Click OK to confirm that the restore completed successfully.
