A Windows Firewall Message Disrupts SynchronEyes Software Communication

Issue

A Windows firewall message disrupts communication between the teacher’s computer and students’ computers.

Cause

Your operating system’s Internet connection firewall is active, and it’s disrupting communication between computers.

Solution

• Disable your Internet connection firewall.

• Set your firewall to allow SynchronEyes software communications.

• Open and enable your SynchronEyes software ports.

1. Click Start > Control Panel.

   The Windows Control Panel appears.

2. Double-click Network Connections.

   The Network Connections dialog box appears.

3. Double-click Local Area Connection.

   The Local Area Connection Status dialog box appears.

4. Click Properties.

   The Local Area Connection Properties dialog box appears.

5. Click the Advanced tab.

6. Click Settings.
