Open ports in Windows

You can follow the below method to open the ports in Windows server 2008 :

1.  Open Windows Firewall by clicking the Start button , clicking Control Panel, clicking Security, and then clicking Windows Firewall.

2.  Click Allow a program through Windows Firewall.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3.  Click Add port. (for example: LDAP)

4.  In the Name box, type a name that will help you remember what the port is used for.

5.  In the Port number box, type the port number. (for example: 50389)

6.  Click TCP or UDP, depending on the protocol.

7.  To change scope for the port, click Change scope, and then click the option that you want to use. (“Scope” refers to the set of computers that can use this port opening.)

Alternatively, you can allow a specific program to communicate through Windows Firewall by selecting Exceptions Tab In Firewall.

By default, the programs are blocked by Windows Firewall to secure your computer. Here’s how to allow programs to communicate through the firewall:

1.  Open Windows Firewall by clicking the Start button , clicking Control Panel, clicking Security, and then clicking Windows Firewall.

2.  In the left pane, click Allow a program through Windows Firewall.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3.  Select the check box next to the program you want to allow, and then click OK.

Typically, after disabling firewall, you can allow all the communication through Windows Firewall. In Windows server 2008 advanced firewall MMC, we can configure different policies for Inbound, outbound and connection security traffic. Please check if you disable Firewall on these three scopes. You can run

the following command to disable firewall:

Netsh advfirewall set allprofiles state off
