Since there is no clear section for this post, it seems most likely that people perusing the Server and Networking section would have experience with Windows SBS 2008 or simply Windows Server 2008. Anyways it seems that the Server I built is blocking access to many websites and is affecting all the computers on my network, I will get "Server Not Found" error in Firefox and similar messages in Safari and IE. This seems to occur mainly on many foreign websites such as those ending in .co.uk or .de even on major sites such as google.de or bbc.co.uk. Also on some of the websites I have access to part of the content is blocked. For example Newegg.com has some images disabled. Newegg with Dynamic IP However on any of the affected computers if I turn off the function of obtaining an IP Address automatically and instead set a Static IP Address and DNS. Then choose my routers IP address for the router and DNS settings rather than my Server's IP address all websites work fine. On my local network I can still access shared folders and remote desktop however I can no longer access company web. Newegg with Static IP Other possibly pertinent information. - This error did not occur until I set up Remote Web Workplace and directed the needed ports through my firewall to my Server. - The Windows Server is my DHCP Server. - DHCP is disabled on my router. - No third party software is installed on my Server, except Firefox and Flash Player. All that is installed is SBS 2008, drivers and any updates through Microsoft update. - Vonage phone hooked up to LAN with necessary ports opened in the firewall and directed to Vonage device. I did not place the device in between the router and modem as it would make my internet connection unreliable. The device has been connected to the LAN for over a year in this manner without causing problems. Background I am not running a business off this server. My use of SBS 2008 is purely academic for the time being. I have been using "Windows Small Business Server 2008 Unleashed" by Eriq Oliver Neale as a guide for learning SBS 08. So the only ports I have opened and directed to my Server are for Remote Web Workplace to function. Since SBS 08 does not automatically act like a router as 03 did none of these functions were enabled. I don't think these functions can be possible with Server 08 without a third party program.
