I have a client with several small pharmacies. Each has an application that handles prescriptions and etc. With this app when certain drugs are processed its supposed to print out some form. In one office that form is not printing. Everything else prints fine. The vendor of that program told me that for this program it checks a website to determine which form to print and that in this location it is somehow getting blocked. (Below is the port and website the app looks to) We don't block and websites or ports. How can I determine what is blocking it in this location and no others. All the sites use Trend Antivirus but it isn't blocking it in any other office.
