I have a mapped network drive, on which I store some programs, one of which I've put in my startup folder.

Unfortunately, this program "does not have a valid digital signature", which means that every time I reboot, I get a security dialog, asking me whether to run it.

I would prefer not to have to copy this program to the local disk.

How can I disable this prompt?

Ok, I found the solution.

  • Go to Control Panel -> Internet Options -> Security -> Local Intranet -> Sites -> Advanced
  • Add the mapped drive or UNC path (eg. Z:\ or \\machine)

Do I remember a box to tick for a permenant connection? – Guy Thomas Nov 13 '09 at 8:20
When mapping the drive, yes. – Blorgbeard Nov 15 '09 at 19:52
Thank you, this is the solution that allows me to finally use my shared VirtualBox folders to keep all of my portable windows utilities. It works on XP too. – Matt Jan 5 '13 at 12:16
Something may have changed (April 2014). The dialog won't let me add a drive letter, e.g. X:\ and X: and file://X: all result in "you have entered an invalid wildcard sequence" (screenshot: (Win7 Home Premium x64) – matt wilkie Apr 11 '14 at 5:09
@matt wilkie To add a whole folder (in this case, the root folder), you should have to specify a wildcard at the target directory. So, it should look like X:\*. At least, this was the case in my experience. – Bret Mar 1 at 19:27

If your Internet Settings are tied down (as mine are), but you have access to the exe, you can try the following in a command prompt:

move oldName.exe > newName
type newName > oldName.exe

That will remove the stuff that causes Windows to care, which, I think, is stored in an alternate data stream.

The top answer didn't work for me I had to change a different setting in the same panel.

What I changed was: From Go to Control Panel -> Internet Options -> Security -> Local Intranet -> Sites -> Advanced (Same as above) In the "Local Intranet" settings window I unchecked "automatically detect intranet" and checked "include all network paths" which will work for me in my virtual environment.
