Avoid security prompts when copying or moving files within your network

Windows may prompt you with a warning when you attempt to copy or move files across systems on your network.

To get around this problem, you will need to tell Windows that the other host computer is a system on your Intranet. Follow the steps below.

Go to Internet Options.
Click on the Security tab.
Select Local intranet and click the Sites button.
Click on the Advanced button.
In the Add this website to the zone: box, type
file://192.168.1.*
click the Add button.

Note: You will need to substitute 192.168.1 depending on your network setup. You may also specify hostnames like file://*.<domainname>.
