You Cannot Play Multimedia Files After SSL Is EnabledSome Web browsers may not support advanced content, such as Macromedia Flash or Windows Streaming Media content, when SSL is enabled. For example, a page may not load, or Flash or streaming media files may not play correctly. You must configure your Web browser, the students', and the teachers' Web browsers to support advanced content when SSL is enabled.To do so, follow these steps:
"Access Denied" Error Message When Teachers Try to Use the Find Feature in Class ServerWhen a teacher tries to use the Find feature in Class Server, the teacher may receive either one of the following error messages:Error 40766.70005: Access Denied Error 4076A.70005: Access Denied Error 40772.70005: Access Denied
To deploy a full P3P privacy policy on the school server, determine how privacy is implemented at your school. The school district may already have existing policies and legal guidelines regarding information associated with students. Inquire whether an online privacy statement already exists for the district, and if it is published on the Internet. When the appropriate policy is determined, deploy the policy on the school server in an Extensible Markup Language (XML) schema that can be read by Web browsers such as Internet Explorer 6.0. For more information about how to implement a privacy policy, visit the following Microsoft Web site: http://msdn2.microsoft.com/en-us/library/ms537341.aspx
(http://msdn2.microsoft.com/en-us/library/ms537341.aspx)

You must specify all headers in the CSV file. Headers are case sensitive.Note Headers that are created by using Microsoft Encarta Class Server's ECS10_Import tool 1.0 do not work with the CSV Import tool 2.0. For more information about how import CSV data, see the Class Server Administrator's Guide (for Class Server 3.0), or see the Class Server 2.0 Installation Guide. "User Name or Password Is Incorrect" Error MessageWhen you use Class Server, you may receive the following message:User name or password is incorrect. To resolve this issue, make sure that the Local Security Policy setting is correctly configured on the server. To do so, follow these steps:
The CSV Import Tool Does Not Import Data to the Correct School When Class Server Is Configured with Multiple SchoolsWhen you import data to a specific school on a server with multiple schools, you must specify the school where you want to import data to. To do so, you can either specify the default school in the Class Server Configuration tool, or run the CSV Import tool in unattended (command-line) mode.To set the default school by using the Class Server Configuration tool, follow these steps:
Create User Domains for the Active Directory Import Wizard in Class ServerWhen you use the Active Directory Import Wizard to import a group, the users in the group must be in the same domain. For example, if you have two groups, you must create a domain for each group.For example, you have the following two groups: Group 1 To import these users to two domains, format the information as follows:
amya maryb Group 2julieb scottc domain\amya, domain\maryb, domain2\julieb, domain2\scottc
By doing so, Domain\Group1 contains amya and maryb, and Domain2\Group2 contains julieb and scottc.
Security Settings Are Not Valid After You Run the Class Server Backup WizardWhen you use the Class Server Backup Wizard to restore school data to the server, and you modify Class Server security settings during the restore operation, the Class Server security settings may not be valid.To resolve this issue, wait until the restore operation is complete before you run the Class Server Configuration tool to specify the new security settings. Recover Data That Is Unintentionally DeletedAfter you delete a teacher account or a class by using Class Server - Administrator, any data associated with that teacher or class is permanently removed from the server. You may be able to recover some or all of your data by doing the following:
Check the working folder on the teacher's computer. If Class Server - Teacher is configured for offline access, you can sign in to offline mode and export the Learning Resources. If Class Server - Teacher is configured to use online-only mode, you cannot sign in, but you can access Learning Resources in the teacher's working folder. See the "How to Locate Working Folders By Using Class Server - Teacher" section later in this article for more information about how to locate the working folder. Recover Learning Resources from the Class Server Computer Check whether the Learning Resource files that you want still exist in your server data folder. Assignments that were created by using a Learning Resource in the teacher's My Learning Resources view are retained as a copy of the original Learning Resource, and are associated with a class. Recover Learning Resources from a Class Server Backup If you cannot locate the files on the teacher's computer or on the server, you may be able to restore a Class Server backup and then recover the files. To restore a backup to recover files, follow these steps:
To assign the ASPNET account the Full Control permission to the data folder, follow these steps:
Troubleshoot Issues With Class Server - AdministratorThis section contains information about how to troubleshoot issues that may occur when you use Class Server - Administrator.Cannot Sign In to Class Server - Administrator After You Try to Perform a "Save & Configure Operation"When you switch your school from Class Server authentication to Active Directory authentication, and then click Save & Configure in the Class Server Configuration tool, you may find that you cannot access Class Server - Administrator if the save and configuration operation does not complete successfully.This issue may occur if Internet Information Services (IIS) is in a stopped state as a result of the unsuccessful save and configure operation. To resolve this issue, see the "Error 40E14: Error -- The Username You Selected Is Already in Use" section earlier in this article. Troubleshoot Issues with Class Server - TeacherThis section contains information about how to troubleshoot issues that may occur when you use Class Server - Teacher.You Are Prompted to Replace the Teacher.msi file When You Reinstall Class Server - TeacherWhen you reinstall Class Server - Teacher, a dialog box is displayed that informs you that the Teacher.msi file already exists, you are prompted whether you want to replace the existing Teacher.msi file. Click Yes on the message to continue the installation.Find Working Folders in Class Server - TeacherTeacher data files are stored in working folders (also referred to as working directories) that are associated with teacher profiles. By default, these working folders are stored in a single location for each Windows user profile. You can find a working folder or change the location of a working folder by using Class Server - Teacher.The Default Path of the Class Server Working Folder The following lists the default path of the Class Server working folder on a computer running Windows Server 2003, Windows XP, or Windows 2000:
Locate Working Folders By Using Class Server - Teacher To locate working folders by using Class Server - Teacher, follow these steps:
Microsoft Windows Installer Unexpectedly Starts When you Install Class Server - Teacher or When a Teacher Edits a Learning ResourceWhen you install Class Server - Teacher or when a teacher edits a Learning Resource, the Windows Installer may unexpectedly start.This issue may be caused by a conflict between the HTML settings in Microsoft Office 2000 and the Grading Tool in Class Server - Teacher. To prevent this issue from occurring, make sure that Web scripting is disabled in Office 2000 on the computer where Class Server - Teacher is installed. To disable Web scripting in Office 2000, follow these steps. Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
You Receive a Warning About ActiveX Security Settings When You Install Class Server - TeacherWhen you install Class Server - Teacher, you may receive an ActiveX warning message.To resolve this issue, modify the ActiveX security settings in the Web browser. To modify the ActiveX security settings in Internet Explorer 6.0, follow these steps:
Synchronization With Class Server is SlowWhen a teacher synchronizes a large number of files with the school server, the synchronization may take a long time. For example, a teacher sends an assignment that includes a 2 Megabyte (MB) attachment to 45 students. When the students complete the assignment, the total file size is 90 MB (45 students x 2 MB). In this situation, additional time is required to synchronize the 90 MB of data with the server.How to Configure a Web Browser to Bypass a Proxy ServerIn some network configurations, Web browser clients are required to use a proxy server to locate resources on an intranet or on the Internet. To preview Learning Resources correctly, Web browsers running on a computer configured with Class Server - Teacher require direct access to the local host address without going through a proxy server. If direct access to the local host is not configured, you may receive the following error message:10061 Connection refused To configure Internet Explorer 6.0 to bypass a proxy server, follow these steps:
Scoring Charts Take a Long Time to LoadWhen you click View Chart to view a scoring chart, a scoring chart that contains a large quantity of numbers may take several minutes to load. To view a scoring chart more quickly, you can click Export to Excel to export the information to Microsoft Excel.Red "X" Appears When You View or Edit Learning Resources and AssignmentsWhen you view a Learning Resource in editing view in Class Server - Teacher or in another program, question components (the parts of a question) of the Learning Resource may appear as red "X"s.This issue may occur when Class Server - Teacher or another program cannot access the http://localhost:3535/ Web address, where the question components are generated by Class Server - Teacher.
