Sharepoint (Mycompanyweb) asking credentials repeatedly

[Faber]

Hi,

We have a server at our office which is running Windows small business server 2011 standard 64 bits. This is our exchange server, we just recently decided to start using sharepoint. (we recently had a backup pronlem on server which was solved by doing some updates on sharepoint and other) We figured that now that it was up to date we might has well use it.

Now the problem is each time we try to reach the website through our web browser (ie, chrome ...) we get a authentication window that asks us for credentials.The thing is if we enter the credentials we'll get asked 7-8 times in a row before i can get to the website.I've browsed several website and tried a couple of things myself but couldnt really find a solution. I've worked with windows server before and i can most of the time find my way around most problems, but not being a iis/sharepoint expert i cant really say where the error comes from.

Ive tried basic solution found online for this problem.- Site is in the intranet zone, or listed as a trusted site in the browser security settings.
- Site custom settings are set : "User Authentication" Automatic Logon only in Intranet Zone
-Checked site configuration. Tried changing authentication method (made no difference, asked 10 times for credentials)
-Cleared all internet history, cache, passwords. Used different computers to check.Ran ie in no add-ons mode
- Turned off Integrated Windows Authentication in Internet Explorer
- In site authentication settings tested clearing the ''Enable Kernel Mode Authentication''
- The ''disableloopbackcheck'' in regedit is set to 1 so this should be disabled and not causing problems

Here is a list of the os/hardware/software/configs we're using.
Windows small business server 2011 standard 64 bits
Sharepoint 2010

Asp.net / IIS companyweb settings :
Asp. net
.net authorization rules : allow all usersNet globalization : invariant language, enable client = falseNet roles : error ( there was an error while performing this operation. Details : a network related instance specific error occured while establishing a connection to sql server. The server was not found or not accesible. Verify instance name is correct and sql server configured to allow remote connexions
.net users : error ( there was an error while performing this operation. Details : a network related instance specific error occured while establishing a connection to sql server. The server was not found or not accesible. Verify instance name is correct and sql server configured to allow remote connexions
Application setting : aspnet:usestrictparserregex true local
Connexion string : local sql datasource=.\sqlexpress;intwgrated security inherited
IIS
Authentication : -windows enabled, extended protection off, enable kernel-mode authentication off.
- asp .net enabled, authenticated user
Authorizing rules : allow all users
Directory browsing: disable
Ssl setting : ignore
.....

Now any help would be appreciated. Like I said earlier we are normally able to find the answers ourselves but it's a first with Sharepoint and we don really know how it is built, any ideas/solutions will be helpful. I'll put a couple pictures of the config, maybe someone will be able to spot where we did something wrong. Thanks in advance.

It seems like you are encountering authentication issues when trying to access your SharePoint website, and you have tried several troubleshooting steps already. Since this is your first experience with SharePoint and it involves integrating it with your existing environment, there are a few things we can explore to resolve the authentication prompts. Here are some potential solutions and recommendations based on the information you provided:

Troubleshooting Steps:​

1. Browser Settings:
   • Ensure the SharePoint site is added to the Local Intranet or Trusted Sites in Internet Explorer settings on the client machines.
   • Check if the browser settings are correctly configured for automatic logon in the Intranet Zone.
   []SharePoint Central Administration:
   • Check the authentication provider settings in SharePoint Central Administration to ensure they match the authentication methods in IIS.
   []IIS Settings:
   • Verify the authentication settings in IIS for the SharePoint site.
   • Ensure only Windows Authentication is enabled for the SharePoint site.
   []Service Account Permissions:
   • Check the permissions of the service accounts used by SharePoint. They should have the necessary permissions to access resources.
   []SharePoint Web Application Settings:
   • Double-check the security settings within the SharePoint Central Administration for the web application in question.
   • Ensure that the web application's authentication settings are correctly configured.
2. Active Directory:
   • Check if there are any issues with Active Directory synchronization or user permissions that might be causing the repeated prompts.

     Recommendations:​

   • Check Event Viewer Logs:
   • Look for any authentication-related errors or warnings in the Event Viewer logs on the server to pinpoint the exact issue.
   • Service Account Configuration:
   • Verify that the service account used by SharePoint has the appropriate permissions and is configured correctly.
   • SharePoint Diagnostics:
   • Use SharePoint Diagnostic Studio or ULS logs to get detailed error messages related to the authentication failures.
   • SharePoint Farm Configuration:
   • Ensure that the SharePoint farm configuration aligns with best practices and that all servers in the farm are functioning correctly. Given the complexity of SharePoint configurations and the interactions between SharePoint, IIS, and Active Directory, troubleshooting authentication issues can involve multiple layers. It's essential to methodically go through each component to identify the root cause. If you encounter any specific error messages or behaviors during this process, feel free to provide more details for further assistance. Additionally, you can upload screenshots of specific configurations or error messages for a more detailed analysis.
