IE 8 / Win 7 ~ Opening Internal Website for 1st Time Results in 404 Error and Authentication Fails.

Hello Experts,
I know this may be hard to track down, because I cannot share the actual site, but any ideas on this puzzler could be helpful!

We have an internal website which uses Windows Authentication when visited. For all other users I've tested, the site opens fine, authentication works, first time, every time.

For me, if I open the site, I initially get a 404 error that the site does not exist, but then if I try the link again, it works (*cant refresh, have to retry the link/favorite). If I close IE, and retry the page, I get the 404 again...

The 404 is:
- The selected page "/misc_folder/project=index.html" is not available on this server.

Also, after retrying and opening the website, I noticed Windows Authentication is not working, and I have to logon each time.

I've tried a variety of IE settings, along with a REIS reset of IE 8, no help. Firewall is fully disabled on the domain. Sorry, I cant say how the site is developed...

Any ideas?

My PC: Windows 7 x32, Internet Explorer 8.

is this this internal website from an application that is installed on the machine or from a website inside you network? Have you enabled any features for IIS on the machine?

This is an internal website hosted on a server elsewhere in the company. I would guess it's Windows IIS 6.0, but I really dont know if another 3rd party site developing software is used, or what...

Unfortunately, I dont have ANY access to the server or any configuration details... :-(

Of course, I could maybe contact the support for the site, but I dont really want to bug them for a single-instance issue. This is a local issue, as only my PC out of many is experiencing the problem...

Did you enable an IIS features on your machine, not the server. If newer authentication modules have been enabled on your machine vs the server I have seen issues on my own machine until permissions were changed on the server, (in my case sharepoint) but I do not know what changed on the server to fix the issue, I was the only affected PC.

Is your HOST file correct for your environment? Receiving the correct IP address, proxy URL, etc.?

Only the IIS management tools are on my PC.

Opening our Sharepoint site works OK, which is also hosted from the same location (but likely not the same server).

HOSTS file is normal also - no additional entires at all. All other sites internal/external "seem" to work OK. At elast I haven't found another site with an issue yet...

Try uninstalling the IIS Management tools and see if that helps.

Tried uninstalling mgmt tools. No go...

Also have some more testing info, which is quite interesting. FYI: Site always appears in "Local Intranet Zone" ~ which is accurate.

On my Win 7 PC w/ IE8 v8.0.7600:
- After checking the error, I wondered if the 404 is derived from failed authentication of some type.
- Under Local Intranet Zone options, I changed authentication to "Always Prompt"
- After retrying the site, I cannot enter my Windows username/password in any fashion (FQDN, shortmane, etc...) and have a successful login. (though note, if I reload the page in the same session, I can login!)
- If I use a different user login, the site opens.
- I logged into my PC with a different username, and the site opens.

On a WinXP PC w/ IE8 v8.0.6001:
- Site opens perfectly, automatic authentication works with *MY* windows username.

So with the info above, I can conclude that it is something in Windows 7 or IE8 only within my profile. I didn't try the "Always prompt" from the other account, and then login using my credentials... Hmm.

More testing...

More info...

I replicated the issue on a second Windows 7 w/ IE8, as well as a Windows Server 2008 w/ IE8... All XP PC's work fine with my login...  By the way, my username is one of the few in the company to have a period in the middle, ie. "First.Last" but I dont think this is the cause...

If I enable "Prompt for Authentication" and put in any garbage info, including inaccurate usernames with "." in the middle, it opens the page fine, only logged out.

Yikes, this is getting more and more confusing.

All in all ~ it seems to be *Windows 7* related and *only with my actual username*.

You have me stumped. Start googling and contact your corp desktop team (if you have one), if not contact MS directly.

Thanks anyway - I'll post back if I actually find out what's causing this. It's only my account and only when on Win7 or Win2008 machines... Very strange.
