Disabling the Windows Firewall is typically one of the first tasks an administrator will performed on a 2003 server. Though it may seem like a good idea to enable the firewall service for additional system security, the 2003 firewall often caused more problems than it fixed.

The firewall can be managed from within Server Manager or the Windows Firewall with Advanced Security MMC, shown below:

The firewall settings can then be imported into other individual systems or GPOs to affect multiple servers.

Microsoft has taken great strides to make the Server 2008 integrated firewall far more powerful, configurable, and reliable than its previous versions. With its rich feature set, the new firewall will give administrators an additional means of combating those nasty network attacks!
