Previously I was working with Server 2003 and managed to lock myself out of the server (I was accessing it remotely) by enabling the firewall.
I want to remotely enable the firewall on Server 2008 without locking myself out of the server (access via RDP) and then selectively add IP addresses to the firewall to exclude. i.e. block specific IP addresses.
Are there any step by step instructions on how to safely do this?
