It's the one thing when I'm configuring things that makes me wince because I know it will give me the business, and I know it shouldn't, but it does, every time. I have no real idea what I'm doing, what it is, how it works, so of course I'm blindly following instructions like a monkey at a typewriter.

Please guide me into enlightenment.

This is a really old message, but if you're still having the same question i could try to answer, but that kind of message is pretty context dependant. For that specific one, it sounds like your program is trying to access something outside your network,, like they have a website they need to access to check for updates or something.

I'm trying to remember the context. I think it was when I was putting in the -arrs, but that doesn't seem right. If I remember the exact circumstance I'll pm you, thanks for responding.
