Test using 262
In the context of the specifications below:
Goal:
Replicate the symptom where as HFS is using port 8080
Attempting to reset HFS port to 80, HFS reflects an error message that
HFS is already using port 80
For this test I added a test for SQL Server which was not installed when
HFS first reflected the aforementioned issue
SQL Server by default will consume port 80.
This gives me an application that will compete with HFS for Port 80
Test 1:
Installed SQL Server 2008 Data Center (Defaults to Port 80).
Tested HFS an it defaulted to 8080 as expected.
Disabled SQL Server.
Attempted to reset the HFS port to 80.
HFS still recognized 80 as being used by another applicaton (not itself).

Memory does not release port 80

System rebooted.
HFS uses Port 80.
Test 2:
SQL Server is disabled (Not active since previous boot).
Paging set to "No Pageing File" on my Boot HD ie drive C:
System rebooted.
HFS executed and uses Port 80.
System put to sleep.
System awakened.
HFS still using Port 80.
System hibernated.
System awakened from hibernation.
HFS still using Port 80.
Conclusion:
Could not duplicate the issue (HFS seeing itself as already using port 80)
I am suspect it may have something to do with Windows 7 managment of port allocation.
