Answer
The agent continues to try all of these basic tasks. The real questions are when and how often the retries occur.
The agent does a progressive back off which begins with a seed period of time; in all cases, this period of time is continually doubled up until a max interval is reached.
Both the seed intervals and the max intervals are defined in the registry and defaults for all intervals are three minutes.
Here are the registry details:
Request type Initial value Max value Configuration Requests
