I was wondering if anyone had any good tips or warnings about turning on the 'built in firewall' for Server 2008. It is presently off. I have everything finished and configured ready to launch my website except a firewall.(my developer overlooked it, uh yeah big mistake!!) I am so scared and worried about turning it on so it does not mess anything up because things are running perfect this firewall is my last huge hurdle. I do know that the most important thing is to make sure Remote Desktop Connection is turned on, so I do not lock myself out of the computer! (its hosted miles and miles away) **I have an Exchange server 2010 running on Server 2008 Standard**. I do have some *SQL database* where people type in info as well that I need stored. Will all these databases and Exchange have to be configured manually? I have heard the firewall will usually pickup what needs to be allowed and not allowed. This is of course if the programs are Microsoft based, making an easier configuration. Is this true? I am so unsure. I just cannot find any real specifics on typical configurations. ( I do know every server is different but I just need some real expert opinions) I have been reading up on the firewall issues but I wanted to give the experts here a chance to help a hardware guy out. This is a family website that will hopefully get us back on our feet, all opinions are welcome. My family really needs to launch this site.
