I've got an odd one for you all. I have about 100 XP SP2 workstations in a Multi-Site AD environment. I rolling out IE7 to our machines and I have noticed an strange behavior on the IE7 machines that I cannot seem to fix. I have the security zones setup in IE as the following (I've anonimized the names): Intranet Zone: *.parent.net child.parent.net *.child.parent.net servername.child.parent.net Essentially I put all machines in the parent domain and the child domain in the Intranet Zone. Now the weirdness beings, when I type in the UNC "\\servername.child.parent.net\share" windows explorer tells me it is in the Intranet Zone, however when I map a drive to that same UNC path windows explorer tells me it's in the Internet Zone. I found a MS KB (http://support.microsoft.com/kb/303650) that states UNC paths with dots in them (IP Addresses & FQDNs) will always appear in the Internet Zone even though you have defined them in the Intranet Zone, but then why are my UNC paths displaying as in the Intranet Zone? I assume this is because I have enabled the "Intranet Sites: Include all network paths (UNCs)" in my IE Settings GPO. Has anyone run into this and figured out a way around it, or am I stuck? I would just reference all my network resources by their netbios name as the KB suggests, but we're in the multi-domain environment and accessing servers from the parent domain requires the FQDN. Thanks for the help!
