Symptoms

You configure a network adapter setting as Obtain an IP address via DHCP on a device that is running Windows Embedded Compact 7. The device does not connect to a network. In this scenario, the IP address is listed unexpectedly as static on the network interface screen. Additionally, the value of the DhcpEnabled interface is 0 if you call the GetAdaptersInfo function to obtain the value.

Cause

This problem occurs because the GetAdaptersInfo function uses an internal function to query the Dynamic Host Configuration Protocol (DHCP) information for the specified adapter. Before this internal function queries the DHCP adapter information, the internal function checks whether the adapter is connected to a network. If the adapter is not connected, the internal function returns without querying the DHCP adapter information. As a side effect, the GetAdaptersInfo function incorrectly assumes that DHCP is not enabled for that adapter.
