Do you have any recommendations for a host-based firewall for W2K3 servers?
Servers are critical to any network and they should be deployed with security in mind. Hardening an OS is as important as putting up a firewall. I do not see any need for host-based firewalls running on servers unless this server is going to be the single point to access the Internet (multi-homed) or used in a non-dedicated mode. There are lot of overheads and access problems associated with using host-based firewalls on Network Servers.
But, if you really have a need for this, server protection products by ISS are something to be considered.
Hope this helps.
