Internal VB .NET web application asking for network credentials every time.

Hello all -

I have an internal web application that runs VB .NET in a Windows Active Directory environment. I have no knowledge of .NET just to be upfront. When a user on the network access the web address it always ask for their credentials. Where do I look to remedy that? Users are using IE 9 or above. The web app runs in IIS 7 on a Win 2K8 R2 box.

Thanks in advance.

It may be hosted internally, but is the website name the same as the active directory domain? What are the authentication settings for the site in IIS?

Does the application use a SQL Server backend?
Is the SQL Server on a different server to the IIS?

If all the above is true then you are probably running into a Kerberos double hop problem, this is where the client credentials are allowed (by default) to hop once i.e. between the DC that authenticates the logon to the webserver but then cannot use the credentials to hop to the SQL Server.
