Open file - Security warning


Recommended Posts


Posted

If an executable is copied to the machine from a remote location (file or web server), or run from a remote location, you will get this warning. To make the warning go away, you have to add this site (either the file server URL or the domain name of the domain you got the file from) to the "Trusted Sites" list in Internet Explorer:

a. Internet Explorer > Tools > Security > Trusted Sites > Sites.

b. Under "Add this website to the zone" specify the name of the server

For example:

- For a local file server, enter "file://server" (where "server" is the name of the file server)

- For a local non-SSL web server, enter "http://server" (where "server" is the name of the web server)

- For a local SSL web server, enter "https://server" (where "server" is the name of the web server)

- For a public web server, enter "*.server.com" (where "server.com" is the name of the web server)

If you need this to apply to all users on the system, you will need to edit the registry directly, creating the following registry keys and values if they do not exist:

a. For a local file server, where "server" is the name of the file server:
Key: HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\server
Value: file
Type: REG_DWORD
Data: 2

b. For a local non-SSL web server, where "server" is the name of the web server:
Key: HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\server
Value: http
Type: REG_DWORD
Data: 2

c. For a local SSL web server, where "server" is the name of the web server:
Key: HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\server
Value: https
Type: REG_DWORD
Data: 2

d. For a public web server, where "server.com" is the name of the web server domain:
Key: HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\server.com
Value: *
Type: REG_DWORD
Data: 2

A reboot is required if you edit the registry directly.

Right, but where did the files come from before they were on this machine? They're getting tagged because they don't have the "My Computer" zone tagged in their metadata, which means they didn't come from a CD nor were created on that machine (according to Vista), so they had to have come from another machine. Where did they come from?
