Hi I havn't been able to solve this problem for 2 weeks now. We launched a new drupal site in late October replacing an aspx site. Google Webmaster tools is showing 11,471 url 404 errors for pages not found. our traffic has dropped considerably. The pages are results of query searches that people have performed on my site. Somehow google crawled all of these search results pages. They are all dynamic aspx pages.
My network administrator has been unable to set a 301 redirect rewriteMAp in IIS. I can't use the webmaster url removal tool as they are all 404's. Is there any other way they can be removed? Or is there a rewrite rule he is not using that could solve this. I was hoping we could use a wildcard rule for all aspx pages. I don't have access to IIS tools.
Any help appreciated
