No login prompt on HTTP webpage, but there is for HTTPS

Dominic used Ask the Experts™
We connect to our Netbotz appliances' web GUIs over HTTP and HTTPS. On some of them the webpage won't prompt for a login when connecting over HTTP, so I can't use the GUI, even though it does prompt (and thus login) if I try HTTPS.

I've tried a number of laptops/desktops (all Windows 7 Enterprise) and an older laptop connects just fine over HTTP whereas my newer, recently Windows-updated laptop and desktop do not. All I get is the header of the webpage, with no prompt to login. HTTPS works fine.

Has anyone seen this before, or can point me in the right direction as to how to fix it? It's affecting my colleague too. It's not a network or a virus scanner issue because the older laptop connects fine and has the exact same virus scanner.

Unfortunately I cannot recall exactly when we first saw the issue.
