I have SharePoint Server 2010 running on a Windows Server2008 R2 box. I am accessing the sites remotely through our ISA firewal using the Alternate Accessing Mapping name for Internetl. Everything works except Datasheet View edits and visual charts in Excel Services.
I think it's because I never set the host header value for the web applications.
How do I set the host header value for an existing SharePoint 2010 site to match the alternate access mapping name? the more detailed the instructions the better.
