couldn't connect to termial server xxxxxx (Redirected Local Devices) error

The ActiveX controls are stored here:

 

 

C:\WINDOWS\Downloaded Program Files\

 

 

I would uninstall or delete the component by going to IE -> Tools -> Internet Options -> Settings -> View Files. It should be located here, if you do not have administrator rights I would ask your F5 folks to install the Installer for you. It can be downloaded from Firepass and will install all controls for you without needing to be an administrator each time.
