* Network enumeration has way too many parameters, so I'm not positive I got
* them right. What I've got so far:
*
* - 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.
