This is a quaestion I have had for some time and it is one that I have always meant to ask about. It has to do with being unable to establish a connection with telefinder, but has nothing to do, as far as I know, with the stock anser of making sure that one is using the HH version of the modem settings.

Basically, a login session proceeds normally, but extremely slowly, and ends with a "host is not answering message" (or something close to that). But that is not the interesting thing about it.

What is interesting is that it happens every second connection. That is, the first time you connect, the connection fails, but the next time you connect, the process proceeds quite well. I have had this occur countless times when I call up tfnet for my mail but it has never happened in using the client software

However it is happening to a fellow using the windows client. He is using a USR robotics sportster14,400 which he used effectively last spring. He has changed nothing (including he is using the old windows client). His set up is identical to one that he used flawlessly for 9 months, and he claims that almost everytime he signs in he gets this flip-flop effect.

Had I not observed the exact same thing on the mac when using mail server, I would not have been so quick to believe him. The fact that this comes and goes on the Mac--lasting for periods of weeks and then mysteriously disappearing makes me wonder if the server software is somehow causing this to happen. After all, the only thing that changed for this custoimer **may be** that I upgraded to server software over the summer.

The obvious advice (that I gave him) was to download the latest tfuser client, and time will tell whether that makes a difference.

But what would cause this? the flip-flop nature of the problem makes me wonder if it has to do with how the modem disconnects rahter than how it connects, the first disconnection somehow resetting the client modem so that the second time it can talk to the server end--but this is just thinking out loud.

What causes this? Does anyone know?
