Your post told what it is. It's the Nortel VPN.
Do share background why you installed it.
I have EacFilt Miniport 6,7,8,9,And 10 in my hardware device manager showing as not working. Can you tell me what this is? Should I just remove them? They are all showing as Nortel Network with the same date of 10-30-2001 and the message that Windows cannot load the driver required (code 31) I have been trying to install a scanner and have had trouble loading the proper driver;thus, I am wondering if this is the default driver for the scanner that windows is trying to install?
