Earthlink not helping.

Is it not obvious?  Say you're running Windows XP, you're an expert, you
just want the settings:

dns servers, mail servers, pop servers/imap servers, news servers, etc.

That's the only way to get past the numbskull OS check, similar to what 
some lame websites do.  Once you're past the OS check, everything else is
the same, but they like to pretend it's not.
