The AX Enterprise Portal is set to http://sharepoint/ep in Microsoft Dynamics AX VPC and combined with 192.168.0.1 IP.
The EP site cannot be accessed after changing the initial IP to other internal IPs.
The way to fix this issue is add host records in local VPC and check the host headers in IIS.
Go to C:\Windows\System32\drivers\etc and Open the hosts file using notepad.
Add one record in the bottom
Go to IIS, Open WebSites –> SharePoint –sharepoint80, Right Click the website and Choose Properties.
In the Web Site Tab, Click Advanced and make sure the sharepoint is in the host header value.
