I have an entry in my hosts file dev.tyler.com that resolves to my local IP. I have used this hostname for a site locally for quite awhile and it has stopped working in IE9. I can still browse to the site using chrome or firefox. If I add a new entry to my hosts file called dev2.tyler.com that site works in IE9. It is just my dev.tyler.com hostname that doesn't.
Can anyone give me some ideas of something to check? When I ping dev.tyler.com it resolves to my local ip as it should. Not sure why this hostname stopped working.
