A. The client receives this warning because the Dfs path contains a Fully Qualified Domain Name (FQDN) as its Active Directory (AD)-stored root. Actually, this message is displayed any time a path to a resource contains a FQDN, not just Dfs paths. To avoid the message, add the domain to the client's list of trusted local intranet zones in Microsoft Internet Explorer (IE). To do so, perform these steps:

  1. Open IE and from the Tools menu, select Internet Options.
  2. Select the Security tab.
  3. Select "Local intranet" and click Sites.
  4. Enter the name of the internal domain (e.g., for all hosts in the savilltech.com domain, I would add *.savilltech.com). Click Add.
  5. Click Close, then click OK to the main options screen.

You should no longer receive the confirmation prompt when opening an executable.
