Dial up not idling out

[999Dom999]

We have a dial up connection to retrieve mail from a POP3 server using POPcon set to retrieve hourly. Ocasioanally the connection stays up until someone disconnects it. The connection is set to idle after 1 min and POPcon is set to release the connection aswell. Have set Sniffer but is not telling us much. Can we restrict the dial out times to during the day but still allow remote access at all times? Does anyone know of anything that could be causing the dial up to stay active?

The dial-up program itself, or one of the users' applications (e-mail, a web client of something etc.) accessing to Internet thru this connection are probably doing a periodic DNS-requery (most of them do). That's usually the most common cause that makes the dial-up connection 'think' that there's someone still communicating.

Try to find out what user application is left open (usually that turns out to be an email client) during the times the connection is 'supposed to be' idle. When you find it out try to disable its 'DNS refresh' feature or extend its refresh period. Some applications won't let you do this and if that kind of thing comes your way, then lower your dial-up connection's idle-off period. You might have to use trial-error for that.
