"Access Denied" Error Message When Teachers Try to Use the Find Feature in Class Server

When 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
-or-
Error 4076A.70005: Access Denied
-or-
Error 40772.70005: Access Denied
This problem may occur if any of the following conditions are true:
  • The school server is not configured with a Platform for Privacy Preferences (P3P) privacy policy.
  • The compact policy header that is sent by the server does not meet the default privacy preferences that are set for the teacher's Web browser, and subsequent cookie-related actions are blocked by the Web browser.
  • The teacher's Web browser is configured to not permit cookies.
To work around this problem, either lower the privacy settings for the teacher's Web browser or deploy a P3P policy on the school server.

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://msdn.microsoft.com/library/default.asp?url=/workshop/security/privacy/overview/createprivacypolicy.asp

For more information about P3P, visit the following World Wide Web Consortium (W3C) Web site:

http://www.w3.org/P3P

For example, you have the following two groups:

Group 1
amya
maryb

Group 2julieb
scottc

To import these users to two domains, format the information as follows:

domain\amya, domain\maryb, domain2\julieb, domain2\scottc

By doing so, Domain\Group1 contains amya and maryb, and Domain2\Group2 contains julieb and scottc.

    3. Sign out by using old profile, and then sign in by using a new profile.
    4. Double-click the exported Learning Resources. By doing so, the Learning Resources are downloaded to the new user profile.
  5. To remove the information that you restored from the server, delete the restore information.

    If you know what you are looking for, you can look for files in the server data folder, and look at the metadata in the Index.xml file to determine whether a file contains items you want. If you find a file that you want, you can package it as a Learning Resource and download it to a teacher account.

    The quickest way to do this is to select all the folders that have Index.xml file at the root and bundle them into one Learning Resource file by using the Makelrm.js tool. For more information about how to do so, see the Microsoft Class Server 2.0 Advanced Authoring Guide. After you bundle the files, download the Learning Resource to the teacher's Class Server - Teacher view. Note that to bundle a folder by using the Makelrm.js tool, the folder must contain an Index.xml file.
