How to Fix: Windows Mail + Socket Error: 10053, Error Number: 0x800CCC0F + GoDaddy Mail Server


When checking email via Windows Mail to the GoDaddy Mail Server you may receive the following error;

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: ‘Your Mail Account‘, Server: ‘‘,
Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10053, Error
Number: 0x800CCC0F

This issue may be due to Vista’s AutoTuning of the TCP stack for performance. You can try the  following;

1. Click on the Vista start orb and type cmd in the Start Search box.
2. The search results will display a program named cmd.exe
3. Right-click on the link and select “Run as administrator”
4. After the command prompt window opens, type “netsh interface tcp set global autotuning=disabled” without the quotation marks, then press Enter.
5. Test your POP account and see if you can download your mail now.
6. If nothing changes, re-enable the autotuning feature by typing “netsh interface tcp set global autotuning=normal”

    Doesn’t work for Xp Home Edition and I still have problems with utorrent uploads not working. I don’ want to spend £25 on a registry cleaner and would like to be able to sort it myself.

      Sounds like an issue with your connection or possibly your router/firewall. The very first thing you should try is connecting your computer directly to your modem and restarting both. Your firewall or ISP may be blocking P2P ports. Enable UPNP (Universal Plug and Play) to have ports opened automatically. As for a registry cleaner, they do not fix anything and the general consensus is not to use them. Removing some unused registry settings is equivilant to sweeping out one parking space in a parking lot the size of Montana. However, if you are dead-set on using one, download ccleaner from Piriform. It’s the last “maintenance” utility you will even need and is completely free.
