Course is not properly tracking lesson progress

Most web-based courses delivered via the DAU Virtual Campus require that you access all pages and links in order to receive credit for completing a lesson. If a particular lesson does not get marked as being completed, it’s likely that a link may have been overlooked within that lesson.

1. Click on the “Tools” menu within Internet Explorer (Keyboard Shortcut: “ALT” + “T”)
2. Select “Internet Options”

4. If you are presented with an option to “Preserve favorites website data,” please uncheck this option.
5. Please ensure that you delete the “Temporary Internet Files” and “Cookies” from the same window; the other choices from this dialog are not required.

“HTTP Status 500” / “Exception report” / “The server encountered an internal error”

The DAU Virtual Campus may generate this type of error message when a connectivity issue occurs between the client (your computer) and the host (our application servers). When a client experiences a dropped Internet connection, it may try to recover the web-based session after the users chooses a link within the website. If the host recognizes that a disconnection occurred, it will disallow the session to resume for security purposes. In order to continue past this error, you will need to start a new login session to allow our servers to re-authenticate your credentials.

To ensure optimal performance, it is recommended that you clear your browsing history and restart Internet Explorer before resuming your course:

Clear your browsing history and start a new login session with the DAU Virtual Campus:

1. Click on the “Tools” menu within Internet Explorer (Keyboard Shortcut: “ALT” + “T”)
2. Select “Internet Options”
3. Click on the “Delete” button that appears below the Browsing History heading.
4. If you are presented with an option to “Preserve favorites website data,” please uncheck this option.
5. Please ensure that you delete the “Temporary Internet Files” and “Cookies” from the same window; the other choices from this dialog are not required.
6. After clearing the temporary files and cookies, please close all Internet Explorer windows to ensure this modification is effective.
7. You may then start a new login session with the DAU Virtual Campus by accessing https://learn.dau.mil/.

Please Note: If the error occurred while taking an online exam, the table of contents may reflect a score of 0%. This merely reflects that your current attempt has been accessed, but not graded; it is NOT a score that is counted against you. After following steps outlined above this paragraph, the system will present you with a “Continue My Test” button when accessing the same exam from the course’s Table of Contents (TOC). Unfortunately, any selections that you have made prior to receiving the error will need to be entered again as our database can only record user selections once the entire test has been successfully submitted to the server.

“Please wait… Communicating with LMS”

This message indicates that your browser is attempting to load Adobe Flash content. If nothing loads on the screen, your computer may not be loading the Adobe Flash plugin properly. This can occur when:

• Adobe Flash Player is not installed.
• The Adobe Flash installation is corrupt, possibly by another browser plug-in.
• Your organization’s security settings block Active X content from untrusted sites.

If you are using a work-issued computer, it is recommended that you consult with your local IT department and ask them to verify that Adobe Flash Player is installed and enabled. They should also ensure that the ‘DAU.mil’ domain is listed as a “Trusted Site” in your Web browser.

Unable to open documents/links contained within the course

The resolution to this type of issue is dependent upon what occurs in your attempts to access the documents or course links:

• A blank window displays:
  This is common when your organizations security settings prohibit access to certain file extensions (i.e. PDF, DOCX, PPT). To address this issue, please add DAU to your browsers Trusted Sites list. This action often requires administrative privileges, so you may need to have your local IT department assist in applying the setting outlined below.
  
1. Within Internet Explorer, click on your “Tools” menu (keyboard shortcut: “ALT” + “T”).
2. Click on “Internet Options.”
3. Select the “Security” tab at the top of the Internet Options dialog.
4. Click on the “Trusted Sites” icon, then choose the “Sites” button below the list of security zones.
5. Ensure that “https://learn.dau.mil” or “*.dau.mil” are added to the list of Websites.
6. After applying this setting, please close all instances of Internet Explorer before re-accessing your course.
   
• Nothing happens when choosing the link / A window flashes and disappears quickly:
  This generally means that your browsers pop-up blocker is preventing the content from displaying. If you hold down “CTRL” while you click on the link, this should instruct your browser to make an exception to the standard pop-up blocker rules and allow the window to open. You may also make a permanent exception within your browsers settings:
  
1. Within Internet Explorer, click on your “Tools” menu (keyboard shortcut: “ALT” + “T”).
2. Navigate to the sub-menu entitled, “Pop-up Blocker.”
3. Click on “Pop-up Blocker Settings.”
4. Add “*.dau.mil” and choose “Close” at the bottom.

In addition to applying this setting, those using Internet Explorer 8 or higher may also need to apply a compatibility setting; please Click Here for instructions.

Unable to access the Virtual Campus from your home computer

NOTE: If you are using a foreign Internet Service Provider, military hosting denies access to foreign ISPs.
