I'm using SharePoint 2007 on Windows 2003 64 bits. The SharePoint Farm contains only one server.
Everything works fine. Except on a Web Application : when I'm connected as Domain Administrator on the SharePoint Server, a prompt ask me credential. On another computer on the network, no prompt.
It's like on the SharePoint Server, on a particular Web App the Domain Admin can't access.
The domain admin is Farm Administrator and Web App Administrator for this Web App.
Any idea ?
