I'm using Windows 98 (IE 5.5 SP1) at home and can access the 1911 forum.
Just a thought but I know our IT department has blocked lots of internet sites that pertain to GUNS, weapons, porno, etc. (whatever they consider politically incorrect). They use different wildcards to block out the sights as well as blocking other servers, etc. I don't think 1911forum has a name that would lead to it being blocked but maybe they have started to block all forum type web sites???
