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.
This issue may occur in any one of the following scenarios.
Scenario 1The 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 2The 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 3The 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 4Values 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.
To resolve this issue, use the appropriate method:
Method 1: Disable the DHCP Server service
Method 2: Make sure that no other device on the network is configured as a DHCP server and run the Change IP Address ToolMany 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:
Method 3: Modify the registry to list the correct LAN adapterImportant 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.
