SYMPTOMS

When two Microsoft Windows Server 2003-based Dynamic Host Configuration Protocol (DHCP) servers are part of the same subnet of a domain, a DHCP client computer that is part of the same subnet incorrectly has active leases on both DHCP servers.

CAUSE

This problem occurs because the DHCP server does not correctly return the leased IP address back to the lease IP address pool when the DHCP client requests for an IP address to the other DHCP server.

Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
