Open File - Security Warning problem with files and applications on mapped drive

I keep getting this message:

"Open File - Security Warning

The publisher could not be verified. Are you sure you want to run this software?
Name: M:\application.exe
Publisher: Unknown Publisher
Type: Application
From: M:\application.exe"

the only options are to run or cancel

If i choose run the program runs without issue, however we don't want to have to do that.

I have tried a variety of solutions but haven't been able to resolve. I have tried adding the server that the file is hosted on to both the trusted sites and intranet zones but it doesn't make a difference. The only thing that kind of gets me to a solution is to go into the Internet Zone and choose custom level and under "Launching applications and unsafe files" choosing "enable (not secure)" . When I do this, I stop getting the prompt but I start getting a general warning from Internet Explorer saying "Your security settings put your computer at risk". I have tried changing this setting in both the Intranet Zone and the Trusted Sites zone but it doesn't make a difference.

Its almost as if I am unable to successfully add the local server to the local Intranet Zone or Trusted Sites zones successfully. Its like IE still thinks the server is in the Internet Zone no matter what I do.

I have tried adding it to the Trusted Sites/Intranet Zone using IP address, UNC path, wildcard, drive mapping with domain suffix and several others. None seem to make a difference. Any help I could get with this would be greatly appreciated.

Also, the OS of the machine is Windows 7 64 bit and the OS of the server is Windows 2008 R2.

Set the environment variable SEE_MASK_NOZONECHECKS to 1.

Be careful - if you do this for the entire computer, it turns off these safety checks for everything.

How do I not do it for the entire computer?

You could write a .CMD to run it:

RunApplication.cmd:
SET SEE_MASK_NOZONECHECKS=1
M:\application.exe
