SYMPTOMS

When you run the Configure E-mail and Internet Connection Wizard in Microsoft Windows Small Business Server 2003, you receive the following error message:
The wizard cannot set the DHCP scope options. Ensure that the DHCP server service is running and that a scope is defined. Alternatively, disable the DHCP service manually, and then configure your client computer IP address properties. For more information about manually configuring client computers, see Help and Support.

CAUSE

This issue may occur in any one of the following scenarios.

Scenario 1

The DHCP Server service is enabled, but the service is not started. For example, the DHCP Server service may stop if the server that is running Windows Small Business Server detects another DHCP server on the network. This situation also may occur if you have manually stopped the DHCP Server service, or if you have set the service's startup type to manual instead of to automatic.

Scenario 2

The DHCP Server service is started, but the DHCP scope does not match the network address of the server's local area network (LAN) adapter. This situation may occur when you change the IP address of the LAN adapter, but you do not run the Change IP Address Tool.

Scenario 3

The DHCP Server service is started, but the DHCP scope is not configured correctly. This situation may occur if you delete or deactivate the DHCP scope, but you do not disable the DHCP Server service.

Scenario 4

Values in the registry list the server's wide area network (WAN) adapter as the LAN adapter. This situation may occur if you switch the IP addresses and the network cables between the LAN adapter and the WAN adapter.

RESOLUTION

To resolve this issue, use the appropriate method:
  • If you do not want to use the computer that is running Windows Small Business Server as the DHCP server for the network, disable the DHCP Server service.
  • If you want to use the computer that is running Windows Small Business Server as the DHCP server for the network, make sure that no other device on the network is configured as a DHCP server, and then run the Change IP Address Tool.
  • If you switched the IP addresses and network cables between the LAN adapter and the WAN adapter, modify the registry to list the correct LAN adapter.

Method 1: Disable the DHCP Server service

  1. Click Start, point to Administrative Tools, and then click Services.
  2. Double-click DHCP Server.
  3. If the service is running, click Stop.
  4. In Startup type, click Disabled, and then click OK.

Method 2: Make sure that no other device on the network is configured as a DHCP server and run the Change IP Address Tool

Many routers, wireless access points, and firewall devices include a DHCP service that is enabled by default. For information about how to disable the DHCP service on a network device, see the manufacturer's documentation.

After you make sure that no other device on the network is configured as a DHCP server, make sure that the DHCP Server service is started on the computer that is running Windows Small Business Server. Additionally, make sure that the service's startup type is set to automatic. To do this, follow these steps:
  1. Click Start, point to Administrative Tools, and then click Services.
  2. Double-click DHCP Server.
  3. If the service is not running, click Start.
  4. In Startup type, click Automatic, and then click OK.
Next, run the Change IP Address Tool to make sure that the DHCP scope is configured correctly. To do this, follow these steps:
  1. Click Start, and then click Server Management.
  2. In the Server Management console tree, click Internet and E-mail.
  3. In the details pane, click Change Server IP Address.
  4. In Change IP Address Tool, type the current IP address for the LAN network adapter in the New IP Address field, and then click OK.

Method 3: Modify the registry to list the correct LAN adapter

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in Windows
  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate the following registry subkey, where {GUID} is the ID of the LAN network card:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
    Notes
    • If more than one GUID is listed, review the DhcpIPAddress or IPAddress registry entries to determine the correct GUID for the LAN adapter, and then note the GUID.
    • Make a note of the external network adapter GUID also.
  3. Locate the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer
  4. In the SmallBusinessServer subkey, make sure that the value of the LANNIC entry is the GUID that you noted in step 2.
  5. Locate the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Connectivity\ICW
  6. In the ICW subkey, verify that the value of the Last_1st_Nic_Guid entry is the LAN adapter GUID that you noted in step 2, and then verify that the value of the Last_2nd_Nic_Guid entry is the external network adapter GUID that you noted in step 2.
