SYMPTOMS
In Windows XP with Service Pack 2 and in Windows Vista, Windows Internet Explorer 7 may not correctly recognize the zone to which a network resource belongs when you access the resource by using a mapped drive. Internet Explorer 7 recognizes the resource as a member of the &quot;Internet&quot; zone instead of as a member of one of the following zones:
 * Local intranet
 * Trusted sites

Therefore, when you try run a script that is on the network resource, you may receive a message that states that the file is not safe to run.

You experience this problem if a fully qualified domain name (FQDN) was used to map the network resource to a drive letter. The FQDN of a network resource takes the following form:
