Problem description
When you browse a website with Internet Explorer on a Windows Server, the page may fail to load completely and display an error: "Content from the website listed below is being blocked by Internet Explorer Enhanced Security Configuration".
Cause
This issue occurs because Internet Explorer Enhanced Security Configuration is enabled by default on Windows Server. This feature restricts script execution, which often blocks website content, prevents pages from rendering correctly, and triggers security alerts.
Solution
The following solution steps apply to Windows Server 2012 and later.
Log on to the ECS instance.
Go to ECS console - Instance. In the top navigation bar, select the target region and resource group.
Go to the details page of the target instance, click Connect, and select Workbench. Set the connection method to Terminal, enter the username and password, and then log on to the graphical terminal page.
Open Server Manager by searching for it in the taskbar.
Disable IE Enhanced Security Configuration.
In Server Manager, click Local Server in the left-hand navigation pane.
In the Properties pane, locate IE Enhanced Security Configuration and click the On link next to it.
In the dialog box, select the Off option for both Administrators and Users.
Click OK to save the settings.
Verify the fix.
Reopen Internet Explorer and browse to the website that was previously blocked. Confirm that the page now loads correctly.
Recommendations
To maintain your server's security, we recommend installing a modern browser like Google Chrome, Mozilla Firefox, or Microsoft Edge for web browsing instead of disabling IE Enhanced Security Configuration.
