Receiving SCRIPT ERROR when attempting to login or test mapping using AD credentials

Products

• Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

• When a user logs in to CB Protection console, they get a login script error
• When attempting to test AD mappings in console, users receive "SCRIPT ERROR"
• Classes.vbs file has grown exponentially in size

Environment

• App Control Server: All Supported Versions

Cause

• Some unknown behavior may have caused the file to grow
• There was a bug in unsupported versions of App Control where "Classes.vbs" under C:\Program Files (x86)\Bit9\Parity Server\Scripts was being overwritten with it's own information numerous times.

Resolution

• Confirm that a supported version of App Control is running
• Restart the App Control services as this file is recreated when the services are restarted
• Check the behavior of the file after restart, does it go back to the default 62kb, shrink, or grow?
• As a workaround, you can set the "Classes.vbs" file to Read Only. This will prevent the file from being overwritten if it's growing
