    I'm running Parallels Desktop 4.0 for Mac on Mac OSX 10.4.11. For my Mac, I have one administrator account, and two managed user accounts. My son uses one of the managed user accounts to run Parallels.

    The issue is that I don't want Parallels to be able to access the internet (more specifically, I don't want my son to be able to use Parallels/windows to access the internet). I know I can turn off the internet in Parallels through the Parallels configuration settings, but it can just be turned right back on. There is no password protection to ensure that the settings aren't changed. Or am I missing something? Is there an administrative password that I can enable to prevent tampering with the Parallels configuration settings?

    Another way to accomplish my goal (no internet for Parallels) would be to turn off all internet access (airport and ethernet) for the Mac managed user account that is used to run Parallels. However, I want to be able to still use the internet on my other two Mac user accounts (one admin and one managed). Does anyone have any insight in how to achieve this?

    In the router, blacklist the MAC address that Parallels uses (block that MAC address from using the Internet).

    Isn't the default to share the Mac's NIC and Mac address?

    Seems to me that this is no different than controlling access on a standalone PC. You need to use separate accounts and some sort of parental control software.

    looking for trash files
    i'd try going into system preferences>network and choosing the two parallels adapters from the 'Show:' drop down list near the top. use the 'Configure IPv4:' drop down below, and choose 'Off' instead of 'DHCP'. after you change the first, click the 'Apply Now' button at the bottom, then repeat for the second using the same method.

    when you have turned both off, click the 'padlock' icon to change from 'unlocked' to 'locked/closed' at the bottom left of the window to make sure only an admin account can turn them back on.

    unless your son has an admin account or your password, that should leave the rest of the system network intact and disable parallels only. best of luck.
