Internet Explorer 9 will not accept cookies from Intranet sites

cookiesinternet-explorer-9intranet

My IE9 (Win 7, 64bit) refuses to accept cookies from Intranet sites.

If I use the "full" name of the server, it will accept cookies.

For instance, if the server is called "server1" and has a full DNS name of "server1.internal.com", then IE9 ignores cookies from http://server1 but accepts them from http://server1.internal.com.

I've changed all the settings I can find to allow cookies, but it still fails.

When looking at any site on http://server1, the "Safety" / "Webpage privacy policy" dialog lists the current page on http://server1 and says that cookies are Blocked. Clicking on "Summary" opens a dialog where I can change it to say "Always allow this site to use cookies", but even though that is set, the browser STILL ignores the cookies!

Any ideas?

  • I can add the server name to "Trusted Sites" but it doesn't solve the problem.
  • In Security, Local Intranet, settings are at default
  • In Security, Local Intranet, Sites…
    • Automatically detect intranet network is checked.
    • I've added this server name to the list of web sites in the Advanced dialog

So far, nothing has worked. I am able to live with the issue because I can use the fully qualified name of the computer, and all is fine. And Chrome and Firefox have no problems…

I had his happen to me. My issue ended up that I was using an invalid character in my local fqdn.

In my case it was underscore.

That name didn't allow cookies to work. When I changed the underscore to a hyphen everything was good.
