3.2.4.2 RRasAdminConnectionEnum (Opnum 1)
If the return code is ERROR_MORE_DATA (0x000000EA), then call RRasAdminConnectionEnum (Opnum 1) (section 3.1.4.2) with the handle passed in lpdwResumeHandle. If lpdwResumeHandle is NULL, the enumeration cannot be continued.
When the method completes with ERROR_SUCCESS (0x00000000) as the return value, the client MUST free the returned buffer pInfoStruct.
