PS. All the tools are free.
I have a Windows Me box with dial-up connection to local
isp. The system absolutely refuses to disconnect the
dialup connection when I am done. The only way out is
to shutdown the machine. Any suggestions on where I
can look to find out why the dial-up disconnect is not working?
Thanks
