When I start the program I get a Network Communication warning from Windows Vista.  What are the potential causes of this message?

 

The program performs three functions at startup that involve network communications:

 

 

When the program does not find that it has been activated on the local computer it automatically looks for the ENERCALC Network License Manager.  While this is happening, the program IS NOT trying to send information about you over the Internet.  In technical terms it is using UDP protocol to broadcast a message over the local subnet that the program is here and looking for other programs of like type.  An installation of ENERCALC Network License Manager is a "like type" program and will make itself known.  The program then performs a short conversation with the Network License Manager to request and receive approval to run (providing enough  seats are available in the user's pool).

 

 

 

If web updating is turned on, the first time the software is launched each day it will check to see if there is a newer version available.  It does this by downloading a file from www.enercalc.com over port 80 using HTTP protocol over TCP/IP.  It does not send any information out over the Internet.

 

 

 

If the program receives notification that a newer version is available it will inform the user.  If the user approves, the web update process will begin.  A web update consists of launching the program file ECWebUpdate.EXE in the ENERCALC program directory.  This program will communicate with both http://www.enercalc.com and http://enercalc.cachefly.net to get the required files for the update.  All of this is performed using HTTP over port 80.
