No redirect for web authentication on some networks, windows 7 64 bit

[KokoLoko]

Dear experts,

I am having trouble obtaining internet access on some wireless networks that require web authentication via an initial redirect. This is on a Lenovo Thinkpad X260 running Windows 7 64 bit.

This issue is particularly frustrating because:
1) This computer can successfully get internet on multiple other wireless networks (including some that do have web authentication via a redirect).
2) Other computers/phones/etc. can successfully connect to these networks to which I cannot.

When I connect to these networks, I am assigned a valid IP address. The "limited connectivity" icon appears in the status bar but "additional logon information required" does not show up (as would be expected and as what happens on this same machine with other networks). When I open any browser, it gives an error about not being able to resolve the server's DNS. It does not redirect to the appropriate logon page as what happens when connecting to the network on other devices.

Any help would be appreciated.

Normally you need to connect then open a browser to login you cant get full access until you login
