Windows 7 Mapped Network Drive dsconnects when uploading to the Internet

[MikeonTV]

We have 4 computers that all run new versions of Windows 7. Each have been connected to a Mapped Network Drive and they all connect fine to the network. Dragging files throughout windows works fine. When we try to attach a file from the network in the browser (as in a GMail message) or upload a file with FTP it disconnects us from the network and from the Internet.

This only happens with 2 of the 4 computer.

It seems like you are experiencing a network connectivity issue with two out of the four computers when trying to attach a file from the network in a browser or upload a file via FTP. This disconnection issue may be specific to certain network configurations on those computers.

Here are a few troubleshooting steps you can follow to address this problem:

1. Check Network Settings:
- Verify the network settings on the problematic computers. Ensure that the network adapters are configured correctly and that there are no conflicts.

2. Update Network Drivers:
- Make sure that the network drivers on the affected computers are up to date. Outdated drivers can sometimes cause network connectivity issues.

3. Disable Antivirus/Firewall:
- Temporarily disable the antivirus and firewall software on the affected computers to see if they are causing the disconnection issue. Sometimes these security software can block network connections.

4. Check for Network Drive Mapping Issues:
- Verify the network drive mappings on the affected computers. Ensure that they are set up correctly and that there are no conflicts with drive letters.

5. Scan for Malware:
- Run a full system scan on the affected computers to check for any malware or viruses that might be causing the network disconnection issue.

6. Reset Network Configuration:
- Try resetting the network configuration on the problematic computers. You can do this by running the following commands in Command Prompt:

     ipconfig /release
     ipconfig /renew

7. Check Event Viewer:
- Check the Event Viewer on the affected computers for any network-related errors or warnings that might provide more information about the disconnection issue.

8. Test Network Connectivity:
- Test the network connectivity using different browsers and FTP clients to see if the issue is specific to certain applications.

By following these steps, you should be able to diagnose and resolve the network disconnection issue on the two problematic computers. If the issue persists, feel free to provide additional details for further assistance.
