I have rebooted my phone, shut down & restarted iTunes, but still get the cant sync error -50 message. Please help

Since downloading the latest version of iTunes on my PC, my iPhone 4s gives an error-50 message when trying to sync. My iPad and touch will sync ok, it's just my iPhone 4s. It says the lateset software is up to date (version 6.1.3) I have rebooted my phone and restarted iTunes multiple times, but can't sync my phone. Any suggestions out there?

iPhone 4S, iOS 6.1.3

From the support document that you linked to the forum with

Error 13, 14, 35 and 50 (or -50)

These errors are typically resolved by performing one or more of the steps listed below:

Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.
