I have SBS 2003 deployed and has been working great for several years. Recently a failure has occurred. On the server I can not access any internal or external http address (even the SBS server homepage). I can access https addresses. I can ping internal and external IP addresses as well as host names (ex. google.com). All workstations connected to network can access internal and external pages (including the home page on the SBS server). I have checked all DNS settings, network settings, reset IE to default configuration, clear all temp files. Any ideas? I am at a loss as to what to try next.
