SUMMARY

After you upgrade a Microsoft Windows NT 4.0 server to Windows 2000, Dynamic Host Configuration Protocol (DHCP) continues to assign addresses, even though it is not authorized to do so.

MORE INFORMATION

This is a feature of Windows 2000. To preserve the mission-critical function of handing out IP addresses, upgraded servers are exempt from Rogue Server detection until the first time the Microsoft Management Console (MMC) snap-in is opened on that server.

After the snap-in has been opened, the server begins sending DHCPINFORM packets, and disables itself until it is authorized in the Windows 2000 domain.
