Disabling Windows firewall

Warning

Disabling Windows firewall completely is not recommended except as a last resort for troubleshooting, or when a fully configured external firewall is present.

In Windows Server 2008(R2), the firewall can be disabled by navigating to Start > Administrative Tools > Windows Firewall with Advanced Security. This will open the Advanced Settings window for the Windows Firewall. Right-click “Windows Firewall with Advanced Security on Local Computer” and open up the “Properties” window, and set the “Firewall State” to “Off” for the three different profiles - “Domain”, “Private”, and “Public”.

Allowing incoming connections

This is described in the Windows firewall management article.

Locked-out

Note that turning the firewall on when there is no exception set for the Remote Desktop Protocol might disconnect your RDP sessions and prevent you from reconnecting to the server. If this happens, you can contact LeaseWeb support with the details so that we can change this on the server locally. You will need to provide the current Administrator password to do this.
