Database Backup from Client Machine in Windows Application in VB.NET 2005

                Dim conn As New ServerConnection(server, uid, pwd)
                Dim oSQLServer As New Server(conn) '--create the SMO server object using connection
                SaveFileDialog1.FileName = db + ".bak"
                SaveFileDialog1.ShowDialog()
                Dim s As String
                s = SaveFileDialog1.FileName
                Dim bkDevItem As New BackupDeviceItem(s, DeviceType.File) ' -- create SMO.Backupdevice object
                oBackup = New Backup()
                With oBackup ' Set the backup object property
                    .Action = BackupActionType.Database
                    .Database = db
                    .Devices.Add(bkDevItem)
                    .Initialize = True
                    .Checksum = True
                    .ContinueAfterError = True
                    .Incremental = False
                    .LogTruncation = BackupTruncateLogType.Truncate
                    .SqlBackup(oSQLServer) ' backup SQL database
                End With</pre>

It's working Fine, but when i am running from client machine the it shows the error Message 'Backup Failed for the Server XXXXXXX'

I was changed the Connection string needed server.

Any Suggestion would be Helpful.

Thanks
