Idle Network Connections Closed

[Dave]

Ever since upgrading to Vista 64-bit Business Edition I have been having
issues when uploading files to various servers via FTP. After 5 minutes
the control connection is dropped.

The software I am using does not support keep-alives. And several of
the server admins SWEAR they don't have their server set to drop idle
connections.

So, I did an experiment where wrote a couple of programs to test things.
One was a TCP listener which just listened for incoming connection
requests, opened up connection and printed anything that came through on
the screen. It never closed the connection unless the connection was
lost.

The second program connected to the listener and then did nothing. Sent
no data, just sat in an idle loop displaying the connection status until
the connection was lost or I cancelled it.

I ran the listener on the wife's computer (running XP) and ran the
sender on my computer. After 5 minutes the connection was closed. I
then ran the sender from my daughter's computer (running XP) and the
connection does not close. So it's not XP and it's not my router.

It has to be a setting in Vista. But try as I might I cannot find
anything in google on this problem.

Can anyone help?

Perhaps it's a general connection problem in Vista. Have you set the
Network Card so that power management is NOT allowed to shut it off
(Device Manager) and set it to maximum performance in Power Options?

That solves a lot of Vista's dropped connection issues.

Yeah, I have all power management turned off because my computer is on
24/7 and *always* doing something (rendering or uploading, or both).

I don't have overall connection issues. I can download files just fine.
No problems with uploading dozens of small files since the FTP control
connection is never idle for more than 5 minutes.

The only connection issue I have is that *ANY* idle TCP connection that
is not sending/recieving data but is just OPEN gets closed by Vista
after 5 minutes.

I do not run any kind of firewall software and I have the Vista firewall
disabled.
