I used the DHCPEXIM tool to migrate a DHCP scope between machines. Now, why is the system not granting any new IP leases?

A. The DHCPEXIM tool (from the Windows 2000 Resource Kit, Supplement 1) lets you move scopes from one DHCP server to another. However, a bug causes the new scope not to grant IP leases. To resolve this problem, perform the following steps:

  1. Start regedit.exe.
  2. Go to HKEY_Local_Machine\Software\Microsoft\DhcpServer\Configuration\Subnets\\[IP address subnet\]\IpRanges\\[IP address start\].
  3. Double-click RangeFlags.
  4. Set RangeFlags to 1, 2, or 3 where
    • 1 = DHCP only
    • 2 = BootP only
    • 3 = Both (DHCP and BootP)
  5. Click OK.
  6. Close regedit.
