How to best eliminate dupe content?

[rustyzipper]

I have a site where my main domain has been dropped from google ("Current page is not ranked by Google", according to the toolbar) since September.

Google had previously spidered my site at machinename.hostingproviderurl, which is still included in google but not deeply spidered.

I want to eliminate anything that might prevent us from getting back into Google. Here are the options I see:

1. Set a hard 404 error on machinename.hostingproviderurl

This is least desirable since I'll lose all search traffic from google at least short term.

2. Set a meta refresh

3. http redirect in http header to domain

4. 302 303 304 redirects? I saw a post about this but my hosting provider tells me this isn't an option on IE.

Anyone have any thoughts on the best approach to get Google to spider the correct site and include me again?

I was glad to see that our main site is listed in froogle.google.com. Should I just wait (how long?), or will one of the approaches I listed above increase my chances of being relisted in google?

Thanks!

That doesn't make any sense... I'd guess that every browser that ever made release knows what to do with a 301/302.

My suggestion is capture all traffic that comes in over your provider's domain and 301 it to your real domain. Something along the lines of this: [webmasterworld.com...] (but remember to include the domain check!)
