877 *
878 * - If the scope is RESOURCE_GLOBALNET, and no LPNETRESOURCE is passed,

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

883 * lpProvider is set, all the network providers should be enumerated.
884 * (This means the enumeration is a list of network providers, not that the
885 * enumeration is passed on to the providers.)
886 *
887 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and the
888 * resource matches the "Entire Network" resource (no remote name, no
889 * provider, comment is the "Entire Network" string), a RESOURCE_GLOBALNET
890 * enumeration is done on every network provider.
891 *
892 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
893 * the LPNETRESOURCE's lpProvider is set, enumeration will be passed through
894 * only to the given network provider.
895 *
896 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
897 * no lpProvider is set, enumeration will be tried on every network provider,
898 * in the order in which they're loaded.
899 *
900 * - The LPNETRESOURCE should be disregarded for scopes besides
901 * RESOURCE_GLOBALNET. MSDN states that lpNet must be NULL if dwScope is not
902 * RESOURCE_GLOBALNET, but Windows doesn't return an error if it isn't NULL.
903 *
904 * - If the scope is RESOURCE_CONTEXT, MS includes an "Entire Network" net
