Issue/Introduction

Can we safely Uncheck the "Allow high-bit characters" (high bit are NON-ASCII characters) check box in IIS Request Filtering?

Environment

ITMS 8.x

Resolution

It may be OK to turn off High Bit characters as long as Computers aren't named with High Bit characters (Chinese).   It's not suggested to make this change if using High Bit / Unicode characters in system names.  For example: Japanese / Chinese languages may have issues if this is disabled.

Fix Text: Follow the procedures below for each site hosted on the IIS 8.5 web server:

• Open the IIS 8.5 Manager.
• Click the site name under review.
• Double-click the "Request Filtering" icon.
• Click “Edit Feature Settings” in the "Actions" pane.
• Uncheck the "Allow high-bit characters" check box.
