Cannot login to SharePoint 2013 Site Host Site Name site

 

SharePoint Prompts authentication Dialog box

Unable to log into SharePoint site, Authentication Dialog Box keeps popping up

My Problem

When I open the browser for http://ecm.lewis.com, the browser prompts me the authentication dialog box and asks for a user id and a password. Although I entered the correct user credentials that had complete farm access, It prompted me three times before throwing back a blank page. After much fact finding, I came up with the following solutions that addressed this issue

Resolution

Resolution 1: Disable Loop Back check.

I noticed the loop back check was not disabled on the server so I disabled the loop back check by running this simple script.

New-ItemProperty HKLM:SystemCurrentControlSetControlLsa -Name “DisableLoopbackCheck” -value “1” -PropertyType dword

Alternatively you can modify the registry manually.

Open a Run Command

Type regedit

Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa in registry and create the dword32 for DisableLoopbackCheck, modify the value to 1.

Resolution 2: Adding a Multistring Registry Key

In summary, solution is modifying the registry and adding a new Multi-String registry key named BackConnectionHostNames in SharePoint server at

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsaMSV1_0 and set the host names with values
