Does the OS not pay attention to DHCP option 114:
This document describes a DHCP option (and a Router Advertisement
(RA) extension) to inform clients that they are behind some sort of
captive-portal device and that they will need to authenticate to get
Internet access. It is not a full solution to address all of the
issues that clients may have with captive portals; it is designed to
be used in larger solutions. The method of authenticating to and
interacting with the captive portal is out of scope for this
document.

- sandworm101 3y agoIt is more layered than that. The work machine initiates a VPN automatically at login. Once that VPN is up, all traffic goes through the VPN, including DNS. It will actively ignore/block anything that isn't coming from the VPN. So we do tricks to get to the hotel splash page before the VPN software wakes up. These are corporately-managed windows machines. The boot/login process isn't exactly quick.
