Scenario 2: Error Page

HTTP Error 404.7 - Not Found: The request filtering module is configured to deny the file extension.

Module: RequestFilteringModule

Notification: BeginRequest

Handler: ExtensionlessUrlHandler-Integrated-4.0

Physical Path: C:\Program Files (x86)\Symantec\Symantec Endpoint Encryption Management Server\CommunicationWS\WebConsole

Scenario 3: Images not loading properly on Login page or other pages

Scenario 4: Web Console Titles are showing as Generic instead of the true names

Cause

The Internet Information Services (IIS) Manager is set to disallow required file name extensions for the Symantec Endpoint Encryption Services website or Some of the Requirements were not installed.

Resolution

There are 3 solutions to this problem. The first 2 methods require the user perform the following steps:

On the Symantec Endpoint Encryption Management Server (SEEMS), open the Internet Information Services (IIS) Manager
In the "Connections" pane on the left, click the arrows to navigate to the following location Server Name > Sites > Symantec Endpoint Encryption Services > WebConsole
Ensure WebConsole is highlighted in the left pane
Double click on Request Filtering in the middle pane

The following steps are specific to each method.

Ensure you are on the Request Filtering screen and are on the File Name Extensions tab
Right click in the white space within the File Name Extensions page
Select Allow File Name Extensions...
In the dialog box that appears, enter a single period
Click OK
Repeat steps 2-5, replacing the period with .asmx
Repeat steps 2-5, replacing the period with .css
Repeat steps 2-5, replacing the period with .html
Repeat steps 2-5, replacing the period with .js
Repeat steps 2-5, replacing the period with .json
Repeat steps 2-5, replacing the period with .map
Ensure the File Name Extensions tab includes all of the rules from the previous steps.

Method 3: Add Static Content to IIS

Make sure Static Content , under Web Server (IIS) is installed on the Server Roles.

After completing one of the above methods above, refresh the WebConsole page on the web browser to see the functioning website.

Method 4: Add .json and .svg to the appropriate SEE Management Server websites

In addition to the above, you may need to add ".json", which will handle the titles, and ".svg", which will handle the images:

Step 1 of 2: In IIS, click on the "Symantec Endpoint Encryption Services" webpage. Then go to MIME Types and add the following entries:

Step 2 of 2: Next, go to the "WebConsole" website, and here add only the .svg entry as shown in the screenshot above.

Note: It is not necessary to add the .json MIME type under "WebConsole".

Once these three entries have been added, the titles and the images should show up properly.
