login prompt for site collection

i need to get rid of a login prompt when i try to access a site collection

using centeral administration...

i created a web application on port 80. i left the host header field blank, but renamed the Load Balanced URL to http://something.server.com
the authentication provider was windows/NTLM.

then i created a site collection on that web application

then i added an entry in drivers/etc/hosts: 127.0.0.1 something.server.com

now when i try to browse to this site, i get a login prompt. no matter what credentials i enter into that box, it keeps popping back up. for three times. after that it presents a blank page.

Have you tried adding the SharePoint site to your Local Intranet Zone or to your Trusted sites in your Internet Explorer options?

Hi greatbear302,

I was having a similar problem and i solved it by installing a MS Fix. Take a look at this thread -

Read it carefully before installing it. Hope that helps.

This is pathetic. If i install a web application WITHOUT MODIFYING load balanced url (which defaults to the server name and a random port), there is no login prompt and i can get in the site collection sitting on that app just fine.

but when i modify the host header (and load balanced url as well-automatic), i JUST CANT get inside the web site collection. it just prompts me for credentials, and i enter them, prompts again....three times! and then blank page. why???

The following technet URL goes deep into this. "...You can create a new site by using the stsadm.exe command-line tool. You cannot use the Office SharePoint Server 2007 Central Administration Web application to create a host-named site collection."

Did you try the MS Fix? I had the exact problems you've mentioned above.

In order to fix this authentication prompt issue on any machine, pleae disable the loopbackcheck on the server. Its a issue with IE due to security update. Please follow below steps to disable loopbackcheck:
  1. Click Start, click Run, type regedit, and then click OK.
  2. In Registry Editor, locate and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  3. Right-click Lsa, point to New, and then click DWORD Value.
  4. Type DisableLoopbackCheck, and then press ENTER.
  5. Right-click DisableLoopbackCheck, and then click Modify.
  6. In the Value data box, type 1, and then click OK.

Please let me know if this helps?

Best Regards,
Yogesh.

We are using SharePoint 2010 Enterprise using NTLM classic authentication, and we are using Active Directory accounts. Neither user is able to login.  I have verified that their permissions exist properly on the SharePoint site they are trying to access.

The user is presented with a login prompt 3 times, and then is presented with a blank screen.

one user have no problem and the rest of our users have problems.

Thanks
