867 *
868 * - If the scope is RESOURCE_GLOBALNET, and no LPNETRESOURCE is passed,

871 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and

873 * lpProvider is set, all the network providers should be enumerated.
874 * (This means the enumeration is a list of network providers, not that the
875 * enumeration is passed on to the providers.)
876 *
877 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and the
878 * resource matches the "Entire Network" resource (no remote name, no
879 * provider, comment is the "Entire Network" string), a RESOURCE_GLOBALNET
880 * enumeration is done on every network provider.
881 *
882 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
883 * the LPNETRESOURCE's lpProvider is set, enumeration will be passed through
884 * only to the given network provider.
885 *
886 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
887 * no lpProvider is set, enumeration will be tried on every network provider,
888 * in the order in which they're loaded.
889 *
890 * - The LPNETRESOURCE should be disregarded for scopes besides
891 * RESOURCE_GLOBALNET. MSDN states that lpNet must be NULL if dwScope is not
892 * RESOURCE_GLOBALNET, but Windows doesn't return an error if it isn't NULL.
893 *
894 * - If the scope is RESOURCE_CONTEXT, MS includes an "Entire Network" net
