I followed your instructions but I do not think it helped me. I took it one step further and added the IP addresses of my workstation VLAN in the hopes that it would have a direct effect and give the code something to pass on. This did not work either.
I am also finding different behaviors with different versions of IE. This past weekend I was testing remotely through and older terminal server, IE8. In this case, which is still the case, I get this URL when going to my site..
https://portal.mtysite.com/Account/Lo...If I clear out everything from /Account... and hit enter (or hit home on the browser), the page loads in a very incomplete way. It lacks a lot of formatting and some images do not apear. Refreshing the page loads a non-logged in version of the site with only a couple of my tabs showing. This is the same behavior as previously reported.
From IE9 which is standard on my workstations, I get the same behavior with the URL but if I hit the root site address (or hit home), the page loads fine and logs in the user.
From IE10, I seem to have no problem at all. I just logged into my Win8 workstation at the office and the page loads and logs me in with no probblem. I cannot seem to break this to reproduce the problem in IE10 but I will keep trying ;-).
Further work on this would be appreciated. If I can help in any way, perhaps allowing you to peek at my site, let me know.
Thanks,
Mike
