Disable "These files might be harmful to your computer" warning? https://superuser.com/questions/149056/disable-these-files-might-be-harmful-to-your-computer-warning I found a fix by changing "internet options" -- so I guess Windows is detecting the "internet" as my own network.. sigh. Click Start / Control Panel / Internet Options Click  Security  tab. Click  Local Intranet Click  Sites  button. Click  Advanced  button. Enter the IP Address of the other machine or server (wildcards are allowed) and click  Add Click  Close , then  OK , then  OK  again. Disconnect, and reconnect the network drive This worked for me, but it's a bummer I have to manually enter IPs here.. it would be nice if Windows could detect this is a local network file copy and skip the irritating (and pointless) warning about "dangerous" files. Sidenotes: If you are using a DNS name to map the network drive, adding the IP address of the server to the zone will not work. You will need to add the DNS name, and vica-versa. When adding an IP address, you can use wildcards like so: 192.168.1.* Whan adding a DNS name, you can use wildcards like so: *.example.com Using Windows 7, I added my IP address with a wildcard: 10.55.25.* Now all the ip's in this range are part of the "Local Intranet".
