I don't think this is a virus or trojan, but I'm having trouble recalling the name of the "feature" which is biting you.

Some modems, and their drivers, have a feature to block redialling of a specific number--I believe this is a requirement for usage in Europe--they don't want automated systems repeatedly dialling a number which may not be another automated system.

At any rate, I believe I've seen this phenomenon posted before--for whatever reason, your ISP's number has been added to this blocked list.

Here's one rather vague reference to this issue:

let me see if I can find a better one.
OK--here's a reference with the proper name for the feature:

See page 33 of this PDF document--or, perhaps better, check the manual for your own modem, online or otherwise, for this feature.
