  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure.

  • To open DHCP, click Start, click Settings, click Control Panel, double-click Administrative Tools, and then double-click DHCP.

  • Provide a range of addresses that is large enough for your needs, and be sure to set a time-out period that will allow addresses to be reused often enough to keep the scope's pool of addresses from being exhausted. A setting of 30 days is normally sufficient.

  • If you are running the MADCAP server inside a domain, it might generate warning messages for granting permissions to the DHCP server. For more information, see Related Topics.

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.
