Hello, I recently reinstalled SBS 2008 R2 on a Supermicro Workstation. This is in my home as an educational project. Something has changed between the first install and the second and I'm not sure what. Originally I had SBS 2008 and Ubuntu on a dual boot using Grub. I took a new hard disk and installed SBS 2008 clean single boot, updated and then installed a couple third party servers... A game server, a Teamspeak3 server and I've configured Remote Desktop Client on my Win7 and Win8 laptops. I have a Frontier DSL Modem/Router with DHCP disabled. It's connected to a Wireless Gigabit Router with DHCP enabled. The Router had port forwarding setup for the server originally with a reserved IP of 192.168.0.104 With that IP I could connect the game clients and my TS3 clients on the LAN and with the WAN IP I could connect to the same servers from the Internet. Here's what's different. When I setup the server using the same NIC, Router, reserved IP etc. I cannot connect from my LAN or Internet. I enabled the DNS server in SBS 2008 and now I can connect to the game server, the TS3 server and Remote Desktop access to the server from inside the LAN. It will no longer connect by using the IP, I have to type in the DNS name "SBS2008". If I try to connect from the Internet I get error messages that the server could not be found or such. I do have the port rules setup in the advanced firewall settings of SBS 2008 and I have added program exceptions. Both of which are set to Public as well. Since I am learning as I go I'm sure there is some service running that shouldn't or one that should but isn't. What else is necessary for SBS 2008 to receive the forwarded port request from the router. I tried using the following for RDP xxx.xxx.xxx.xxx/SBS2008 but it said the / was not allowed. I used xxx.xxx.xxx.xxx.SBS2008 and just the IP by itself. Any tips on where I can look next or reading material that will fill in the blanks would be greatly appreciated.
