I guess the only way to find out for sure is to do some serious testing.

>>It's the situation where a DBF is opened but its CDX is not and no error message is returned that makes me think of file handles. I've seen this kind of behavior before. My experience is that when there are physical network problems you get some kind of error message from either FoxPro or your network client.

>Depends on the network settings....when I've had problems like this, you never saw an error from the network...and the combined files settings were around 200.But, by George, we could sit there and plot the times of the errors and they corresponded wonderfully to 8:05am (everyone logging on, checking email and such), 11:45 (people logging out for lunch, emailing to find out when/where lunch was gonna be), 1:30 (everyone getting back) and 2:45 (right before afternoon break).
