Help removing duplicate content from the index?

[ccorlando]

Last week, after a significant drop in traffic, I noticed a subdomain in the index with duplicate content. The main site and subdomain can be found below.

http://mobile17.com

http://232315.mobile17.com/

I've 301'd everything on the subdomain to the appropriate location on the main site. Problem is, site: searches show me that if the subdomain content is being deindexed, it's happening really slowly. Traffic is still down about 50% in the last week or so... what's the best way to tackle this issue moving forward?

go to WMT and remove subdomain.domain.com

this will remove the whole sub domain. You will see some text saying remove site when you enter the root, (root of the subdomain that is)

Thanks for the quick response... I'll give this a try...
