Can't seem to find a way around this. I run a digital signage PC for a restaurant and connect remotely to update etc. They've added me to the "approved" list of PCs that can stay connected but every 8 hours I get a browser popup like normal guests to "continue to the internet". which often pops up over the digital signage content that's playing and I get a call. The owners say the "computer guy" doesn't know how to fix it. I've closed the browser, it reopens after set time. I've minimized the browser, also doesn't work. My question is, how is it triggering the browser to open? Can I disable this on the client PC?
