Parental controls are typically only used in home environments, and domains are only used in business environments. Lots of geeks like me have domains at home, though, and it can be frustrating when home features are disabled in domain environments.

By default, parental controls (features that enable you to limit how and how long your kids can use the computer) are disabled in a domain. To enable them, follow these steps:

1. Click Start, type gpedit.msc, and then press Enter. Provide administrative credentials when prompted.
2. In the Group Policy Object Editor, expand Computer Configuration, Administrative Templates, and Windows Components. Under Windows Components, click Parental Controls.
3. In the right pane, double-click Make Parental Controls control panel visible on a Domain.
4. Click Enabled. Then, click OK.

Now, you can edit Parental Controls by following these steps:

1. Click Start, and then click Control Panel.
2. Click User Accounts and Family Safety.
3. Click Parental Controls.
