This file is in a location outside your local network

Question

If I launch my application from one network folder, I don't get a dialog.

However, if I copy my application to a different network folder, and try to launch it, I get the "Open File - Security Warning" dialog displayed below:

If you Google:

• Open File - Security Warning dialog box or
• This file is in a location outside your local network

you'll come across pages that talk about Intranet versus Internet zones, registry edits, Group Policy changes, or even Microsoft Access.

I don't want to deal with any of that if possible. I need the solution to work across 100's of computers that will be launching this application from the network, and I can't make a system change to each of those computers.

1. Why am I getting that dialog if I launch from certain network folders but not others?

2. How can I prevent that dialog from popping up?

Please mention multiple possibilities if applicable.

Answer 1

I just ran into this problem myself while trying to open some JavaScript files on a development storage Azure blob which I have mapped as a drive in Windows Explorer, I fixed it by going to:

Control Panel > Internet Options > Security

Then selecting Local intranet, clicking on Sites, unchecking

[ ] Automatically detect intranet network

and checking both:

[x] Include all local (intranet) sites not listed in other zones and

[x] Include all network paths (UNCs).
