Consider the following scenario:
- You are running Microsoft Internet Security and Acceleration (ISA) Server 2004 or Microsoft Internet Security and Acceleration (ISA) Server 2006 on a computer that has only one network adapter installed. This is known as a single-homed configuration. Typically, you use this configuration if the following conditions are true:
- When ISA Server is located in the internal corporate network or in a perimeter network.
- Another firewall is located at the edge that connects and protects corporate resources from the Internet.
- A temporary network failure occurs. The network outage lasts for more than three minutes.
- When the network connection is restored, the following event is logged in the Application log:
In this scenario, client computers cannot communicate with ISA Server until you restart the Microsoft Firewall service.
Note To restart the Microsoft Firewall service, use either of the following methods.
Method 1: Use the Services console to restart the Microsoft Firewall service
- Click Start, click Run, type services.msc, and then click OK.
- Right-click Microsoft Firewall, and then click Restart. If you are prompted to stop dependent services, click Yes to enable Service Control Manager (SCM) to correctly restart the dependent services.
Method 2: Use the command prompt to restart the Microsoft Firewall service
Type the following commands at a command prompt. Press ENTER after each command.
net stop fwsrv /y
net start fwsrv
Note The /y switch that is in the net stop fwsrv command enables SCM to stop the dependent services.
