Resolution
The cause for these issues is a program that monitors the Winsock protocol for Windows conflicting with Apple software. These programs usually use a Layered Service Provider (LSP) that can help identify the particular program installed. The programs that monitor this protocol have a variety of purposes, including security software, content filtering, and optimization of network traffic.
To find the LSP:
- Download Autoruns for Windows from Microsoft
- Look for Autoruns.ZIP and open the compressed folder.
- After reviewing the contents and the license, drag autoruns.exe to the desktop.
- Open Autoruns.
- Click on the tab that says Winsock Providers.
- A list of items should appear. A column showing the publisher should be available.
- For items other than Bonjour, which is from Apple, check with the publisher for updates to resolve the conflict between their software and Apple software.
- If the publisher is unfamiliar to you, you may be able to use the table below to find out more information about the origin of the modifications to Windows.

- Once you've identified the third-party software that installed the LSP, you should check for updates. If the software is your security software, see iTunes: Troubleshooting security software issues for additional information.
- Bytemobile is usually associated with cellular data connection software. You may want to check if your provider has instructions to disable or uninstall that portion of the software, such as these instructions from AT&T.
- Note: If unsure on the origin of your LSP, you may try to locate vendor information to determine which software is responsible for the non-default value here.
