Error 771 - The connection attempt failed because the network is busy.


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.


Use a regular phone to dial the number from your connection.. Does it ring like a modem? or just ring and ring and ring? or a fast busy signal?

If a modem answers, then time to check your connection, maybe a few commas after the phone number to give it a bit more time, reducing the speed from 117200 to 38400, or possibly an initialization string for your modem.

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.
