Error 774 The connection attempt failed because
of a temporary failure. Try connecting again..
This error is usually a dial up networking error but the cause many times is a related program that has control of your
modem (eg: procom, voicemail software, fax software that is minimized or still running).. Check for applications first.
Reboot the PC if possible, and reconnect, making sure there are no competing applications open.
If the problem still exists (and you've installed nothing new, made eny changes, etc.. deleted your dial up connectoin
and recreate it, if it still doesn't work, remove and reinstall Dial up Networking, and as a last ditch, maybe
uninstalling and reinstalling the modem will help.
