Question

Can't Auto Logon to Intranet site using Internet Explorer

Asked by: mrwolf

Hi Experts,

I have had 3 users recently that can't access intranet sites using IE. When they navigate to the URL it brings up a login prompt. If they put in their domain credentials then they can login successfully but all other users in the domain can log in automatically.

If i log on to a terminal server using their credentials i can access the intranet sites without any prompts so means it is something on the laptops itself. I am pretty sure it is client side because for all 3 users they have had their laptop recently re-imaged and they could access the intranet sites fine before the re-imaging.

For one user i was able to resolve this by going into the Advanced options in IE and removing the "Enable Integrated Windows Authentication" option, restarting IE, adding that option back, then restarting IE but this has not worked for the other 2 users.

All running IE 7 and XP Pro

Is there anything else i can try to get this working? Atm i would like to get it working with IE 7 because installing IE8 has caused other issues in our environment

Is this from inside an environment (e.g., work network).  Have you checked on the terminal server (or a computer that doesn't require the username/password) if Internet Explorer may be directed through a proxy server?

When you are opening the site , in the right side botton, are you finding the this site is in trusted site ?how it behaves for other users ?

If not, try adding this site to the trusted site in IE

 

by: mrwolfPosted on 2009-10-29 at 19:49:00ID: 25699898

Hi,

1. This is from inside a work network.
2. The laptop and terminal server both use a proxy server but internal addresses are in the exceptions list.
3. The sites are trusted since they are on the intranet
4. Only these users are affected out of 80 users

Thanks you for your help

I mean to Say, is this Site is Added to the trusted List in IE> Tools > internet options > Security > Trusted Site

 

by: mrwolfPosted on 2009-10-30 at 00:08:26ID: 25700616

Hi,

No the site is not in the Trusted Site area. But it isn't on the terminal server either.

I will try and it in next time i can speak with the user (they are remote and now it is after hours).

Sorry for the late reply, i have been on-site today and got caught up.

Are there any other suggestions about what it could be?

Are these laptops being logged on with cached credentials?   Are you sure that the authentication is reaching the domain controller.   We had laptops that the person was constantly using cached credentials, and they never changed their password. So the DC didn't authenticate them, but they were able to logon to the laptop which didn't enforce the password changes.   I'm just guessing, but this may be something to look at.

Hi,

The users were busy today so i could not try out a couple of the points mentioned here.

I will try to get this done tomorrow so i can give you an answer. Thank you for your time.

 

by: mrwolfPosted on 2009-11-02 at 23:19:58ID: 25726637

Hi,

1. I tried adding it to Trusted Sites but it didn't work
2. I tried resetting their password and making them sync with the DC but didn't work.
3. I also updated to IE8 and patched it but didn't work

I found the problem to be profile specific. For example, if i logged on to the same laptop i was able to view the sites with no problem.

So i made a backup of the users profile and then renamed it and got them to login again to re-create it. Under this new profile they were able to auto-logon without a problem so i just copied over their profile data to the new profile and tested it again and it works.

In my case, re-creating the user profile has solved the issue but i believe there are some useful troubleshooting steps here for people with a similar problem.

Thank you all for your comments.
