I have a mini-network at home where I work. My main computer runs Win2K and
has FB 1.5.3 SS running. I also use my laptop as an FB server and client for
testing back and forth. For a quick test, I opened IBOConsole on the laptop
(Windows XP Home Edition Version 2002 SP2), connected to my main computer
and then connected to a database. I didn't select anything else in
IBOConsole, views, tables, etc. I just let it sit on the database name.
After a little over an hour, I clicked on the tables and voila, I get the
same error about the connection being closed.

I am going to try it again (I have only done it once so far) but I thought
it might be important to let someone know that I saw the same problem occur
at least once in a simple environement without any MS server software
running.

Now, at the same time that I was just letting IBOConsole sit there, I was
listening to Rush through a stream on the Internet on the laptop. Therefore,
the network card can not be a factor since it was continually being used for
the streaming.

I will continue some further testing and if I can confirm this using
IBOConsole as well as one of my own programs, I would like to ask for more
guidance in helping track down this type of problem. I'm not an FB guru and
I don't have the means to compile C source. (I'm a Delphi guy through and
through :)
