Just a quick post related to an issue I've been having.

I use a Linux server to manage my home network, it's a combination SAN, bittorrent, x2go, backup box.

I keep all my installers on this and share them out to my Windows computers using Samba. For the past year, I've been having trouble installing items, I have the share open to internal PC's, but when I try to run as admin, the permissions fail. I assumed this was some sort of Windows update issue, but come to find out, it's Samba.

Add this line to your /etc/samba/smb.conf file, in the [global] section:
        acl allow execute always = True

This will fix the issue and allow you to access files under your admin account.
