My customer's network is designed to enforce business users to only access web applications with FQDN. Business users can only access SharePoint site with FQDN example: http://abc-intranet.abc.local
abc-intranet as the computer name and 'abc.local' as full domain name.
On SharePoint server, we can't access any SharePoint site using FQDN. Pages and everything can be accessed with only server name example, http://abc-intranet
From all business users laptop, they can ping both abc-intranet and abc-intranet.abc.local. I have never faced this type of issues before and stuck in between, cannot find a right direction to move ahead. Your any help is highly appreciated.
