www.listal.com/groups vs. listal.com/groups

Okay, so when I type www.listal.com/groups into my browser it takes me here to the forums.
When I type listal.com/groups (without the www at the beginning) it takes me to this page:
www.browsercast.com/custom/branded-wwwcom/affiliatereporting/searchboxes/searchstyle_www.html?action=search&afID=5589&keywords=%20groups
I've tried this on Firefox and IE and with two different ISPs so it's not a browser or isolated DNS bug.
Any idea why this is happening?

I think I have it figured out (maybe). The same thing happened to me with other links (like /members). I think there's a problem with the redirect (Apache?)... it's replacing the "listal" with "www" instead of "www.listal" in the URL.
That goes to www.com, which redirects to the link you're talking about.

FYI, this problem seems to have resurfaced.
