+ *
+ * - If the scope is RESOURCE_GLOBALNET, and no LPNETRESOURCE is passed,
+ * all the network providers should be enumerated.
+ *
+ * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
+ * and neither the LPNETRESOURCE's lpRemoteName nor the LPNETRESOURCE's
+ * lpProvider is set, all the network providers should be enumerated.
+ * (This means the enumeration is a list of network providers, not that the
+ * enumeration is passed on to the providers.)
+ *
+ * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and the
+ * resource matches the "Entire Network" resource (no remote name, no
+ * provider, comment is the "Entire Network" string), a RESOURCE_GLOBALNET
+ * enumeration is done on every network provider.
+ *
+ * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
+ * the LPNETRESOURCE's lpProvider is set, enumeration will be passed through
+ * only to the given network provider.
+ *
+ * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
+ * no lpProvider is set, enumeration will be tried on every network provider,
+ * in the order in which they're loaded.
+ *
+ * - The LPNETRESOURCE should be disregarded for scopes besides
+ * RESOURCE_GLOBALNET. MSDN states that lpNet must be NULL if dwScope is not
+ * RESOURCE_GLOBALNET, but Windows doesn't return an error if it isn't NULL.
+ *
+ * - If the scope is RESOURCE_CONTEXT, MS includes an "Entire Network" net
+ * resource in the enumerated list, as well as any machines in your
+ * workgroup. The machines in your workgroup come from doing a
+ * RESOURCE_CONTEXT enumeration of every Network Provider.
