Office applications requesting Authentication for SharePoint
Had a problem recently with SharePoint 2010 when we changed our main way of accessing the site to a public domain name. This change made all Office Applications 2007 and 2010 request authentication when opening and saving to or from SharePoint.
After a longer research into the issue I found this Microsoft KB.
In there Microsoft informs about how WebDav secures sites or networks. I always knew that SharePoint uses WebDav to share documents to Office applications however I had no idea that you had to specify a trusted location if it uses an Internet FQDN instead of a local netbios name.
So I followed the KB and I actually deloyed the registry key via Group Policy Prefferences and after people restarted their PCs no more calls about having to authenticate.
Thanks,
Andreas
