Are you using the Kaspersky Firewall? If so, you need to set up an exception for either you subnet, or the application.
Although, if you Pause Protection, it should not disconnect, because that stops all of the modules. Have you called support?
I've tried everything... disabling the firewall... enabling it and making rules, opening all udp and tcp ports (using the rules templates).
Disabling every KAV services does not solve anything. Only uninstalling does...
Actually the server DOES respond, except for the "login" line that never comes....

Using the native vista client, it ALWAYS works :

Any help appreciated...
Thank you !
