I am running server 2003 ent edition domain. I have few questions for windows firewall:
-One of my servers is running VPN server and has RRAS enabled and I do not want it to be disabled as it is working as the router for my Lan and external connections. My firewall at the moment is Cisco_2811 router. I tried to enable windows firewall on this server and it gives me "windows firewall cannot run because another program or service is running that might use the network address translation component ipnat.sys". If I have to enable firewall anywhere else I need help?
-Should I use the windows firewall on all my servers ? If I enable it on exchange users cannot see the logon page in OWA.?
-FOr my other servers which do not run VPN servers should I enable windows firewall ? is it feasible to use on a server 2003? how secured?
