When the firewall is active I am unable to use the HP scanning utility for my HP Officejet Pro 8600. I have tried adding many .exe's from the HP > Bin folder to the allowed list in the firewall but I still have to disable the firewall for it to even start scanning. It is connected via ethernet to my router, as is the laptop I am trying to scan from. I get the error shown in the attachment. Can anybody help please?
