Turning off Compatibility mode by default for Intranet sites

Turning off Compatibility mode by default for Intranet sites

After updating to patch 11.5.9 you may encounter the following issue with IE 8 and IE 9 browsers accessing your intranet site. This is caused by the browser deciding to load the intranet site in compatibility mode. An example of this behavior can be seen in the screenshot below. Follow the instructions in this KB article to resolve this issue by overriding the compatibility settings for any IE browser accessing your intranet site.
