Today I can't access the internet from my PowerBook, using my uni dorm ethernet connection. iChat AV and Mail work, but web browsing, MSN and Fire do not. I can still browse the SMB network in the Finder. This post is coming to you from Netscape, which is the only browser I have (out of Safari, IE, Camino and Netscape) that currently works! I know that it doesn't use the network settings information, but it's own version, and is automatically configured to retrieve the network proxy settings from a website. However, I can't get those settings to work when I plug them into the network preferences proxies panel (Safari says "can't find server"). If I disable the proxy settings (for HTTP, HTTPS and FTP), I can access my local university pages but nothing on the internet. When I enable the proxy settings again, I can't even access the local intranet pages. The thing I don't understand is that the proxy ports and settings are the same as they were before. This was all working fine until this morning so I'm not sure what's going on. The only thing I did was type in that Terminal code line to enable fast boot-up of 10.3.2. It worked and has cut boot times to 45 seconds, even though I don't know what it did, but I hope it hasn't caused this problem! Anyone any idea what is going on? I could contact my local IT helpdesk, but I'd have to wait 'til Monday and they don't support Macs. Thanks.
