> Description:
> the APP_MAX_DELAY has been set to 5000 ms. However, default firewalls on
> popular platforms such as Windows XP SP2 and Windows Vista filter out
> responses to multicast requests after 3 and 4 seconds. This means that
> clients running on those platforms will fail to discover devices from

> adjust their behavior to the standard, but until then, it is an
> important issue.

> Proposed resolution:
> Either reduce APP_MAX_DELAY or modify default behavior of Windows firewalls
