Turn on Windows 2008 Firewall

If Windows Firewall must be tuned on, Notifications must be enabled during the installation and configuration. Users are notified when a program encounters a blocked port. Create a permanent Windows Firewall Rule for allowing the program to communicate on the specific port and grand access to users.

Enable Notifications

Follow these steps:

1. Open Windows Firewall.
2. Go to Start, Run, and enter firewall.cpl.
3. Select Change Notification Settings.
4. Select Notify me when Windows Firewall blocks a new program.
5. Click OK.

Allow Access

When Notifications are enabled, the user is prompted the first time that a program attempts to access a protected port.

To allow access, click Allow Access. Windows Firewall creates a Rule and the program is permanently granted access on the required port.

Allow ICMP

Another Windows Firewall setting that you must adjust is to allow ICMP (PING) to work while checking communication between the various servers.

Follow these steps:

1. Open Windows Firewall.
2. Select Advanced settings.
3. Select Windows Firewall Properties.
4. Select the IPsec Setting tab.
5. Change the IPSec exemptions, Exempt ICMP from IPsec value from No (default) to Yes.
6. Click OK.
7. Close the Windows Firewall, and Windows Firewall Properties windows.
