  • Performing this task does not require you to have administrative credentials. Therefore, as a security best practice, consider performing this task as a user without administrative credentials.

  • To open a Control Panel item, click Start, click Control Panel, and then double-click the appropriate icon.

  • Do not use this procedure to specify the numbers required before dialing to a different city, area, or country/region, such as 1, 0, 00, or 011. The numbers specified here are to dial local or long distance calls from within a private branch exchange (PBX), such as used by a company or other organization. The dialing rules for a location automatically insert the number required to call a number with a different city, area, or country/region code.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
