I have been away for the past few days so I haven't had the chance to also thank Bertling for his suggestion as well!<br />
Will try the software and get back with info!

We are going to put our servers behind a cisco ASA firewall and I would like to know whats the easiest way of finding out which ports are currently being used on our Windows 2003 machines. In theory I can research online to see each software that we run what port it uses (and close everything else), but in practice this will definitely mean we will &quot;forget&quot; some ports and so our applications/services will not work.<br />
<br />
Other than the standard and well known port 80, 21 and so on so forth, is there an application I can use to show me which ports are currently being used?

How to tell what ports are being used so that I can avoid our Cisco Firewall blocking them?

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
