We have a SharePoint installation for one of our clients with external access enabled using https via ISA server. When accessing the portal internally within the intranet/domain its fine. In case of external access using https when users login to portal adn when they try to open a MS Word (or any Office) document they are prompted to to enter their username and password again. It happens for every MS Office document. We are using MOSS 2007, Office 2007. I know that the promp for re-authentication is is due to the fact that office try to open a new session but is there any work around to overcome this.
Any help will be highly appreciated.
