I have a new iMac, just installed Net Nanny, and now all the user accounts that are monitored will not access secure servers. The two admin users have no problems. Does anyone know why this might happen?

You need the original install disks for you OS. Start the install process and then use the Password Reset tool to change the admin password. Once you are able to log in as admin, you should be able to see your old account in the System/Users folder. You should be able to directly access it, or you should be able to use the "Get Info" on the account's folder and change the permissions that way.

1. Run "lusrmgr.msc" to reset Dell Windows password.
In Windows 8/7/Vista/XP, there is an easy way to reset a forgotten user account password by just run the lusrmgr.msc. But you need to login your server or laptop with an account which has admin privileges. Note that resetting password with this tip might cause irreversible loss of information for the user account. This data loss will occur the next time the user logs off. You should use this command only if a user has forgotten his or her password and does not have a password reset disk.
Step 1. Start your PC and log on with an available user account which has admin privileges.
Step 2. Click "start" button, press "Win+R" to open "Run box". Type in "lusrmgr.msc" and hit Enter.
Step 3. Local Users and Computers appears, all user accounts of your computer will be list, right-click your user name and select "reset password".
Step 4. Type in a new password and type it again to confirm it, click OK.
After restarting you can login that user account with new password.
2. Remove Dell password by using a Windows password recovery tool.
This is a universal way to reset forgotten Windows password on HP Server or PC, no matter what your Windows system is, Windows 8/7/vista/XP. iSunshare Windows Password Genius is designed to recover Windows password for any kinds of PC, such as hp, dell, acer, Toshiba, Lenovo, IBM etc. It not only can help reset server or laptop password Windows 8, but also Windows 7, Vista, XP and Windows 2000.

Im assuming you are using outlook express, if not, I apologize, but steps should be similar for other types of software:

1. On the Tools menu, click E-mail Accounts.
2. Click Add a new e-mail account, and then click Next.
3. Click POP3, and then click Next.
4. Under User Information, do the following:
1. In the Your Name box, type your full name the way that you want it to appear to other people.
2. In the E-mail Address box, type your e-mail user name, followed by @bellsouth.net.
5. Under Server Information, do the following:
1. In the Incoming mail server (POP3) box, type mail.bellsouth.net.
2. In the Outgoing mail server (SMTP) box, type mail.bellsouth.net.
6. Under Logon Information, do the following:
1. In the User Name box, type your full e-mail address, including the @bellsouth.net domain.
2. In the Password box, type your password.
3. Select the Remember password check box.

Note You have the option to have Outlook remember your password by typing it in the Password box and selecting the Remember password check box. Having Outlook remember your password means that you won't have to type your password each time you access the account; however, it also means that the account is vulnerable to anyone who has access to your computer.

1. To verify that your account is working, click Test Account Settings. If there is missing or incorrect information, such as your password, you are prompted to supply or correct it. Make sure your computer is connected to the Internet.
2. Click More Settings.
3. On the General tab, under Mail Account, type BellSouth.net.
4. Click the Outgoing Server tab, and then select the My outgoing server (SMTP) requires authentication check box.
5. Select Use same settings as my incoming mail server, and then click OK.
6. Click Next, and then click Finish.

Notes

• Do not select the Log on using Secure Password Authentication (SPA) check box.
• Unless specified by BellSouth.net, all server and address entries are typed in lowercase letters.

Thanks for the clarification.

The best advice I can give is to either reinstall Safari for that user or install a seperate browser such as firefox for this account. The odd thing is that it isnt in the applications folder, because that would imply it doesnt exist, but as you say it works for the administrator?

Try logging on as the user, installing safari or an alternative browser and adding it to the dock for ease of access and let me know how you get on with that. If it doesnt work, I will think of another way to sort your issue :D

here's some documents

or online version
How To Customize Net Nanny Accounts and Settings

Even though the download says "allows all users" your wife's user account is completely separate from yours. You will have to download Firefox in your wife's account.

Create the New Account(User), and Configure all the new settings.
