My website is on a Windows server which is causing me a lot of issues with trying to get 301 redirects onto all the 404s I have. Basically the webmaster says its almost impossible to sort out the 404 pages without moving to a Linux server.... this in itself is troublesome due to the many emails and domains that are already there.
My question is am I really being hurt from my 67 different 404s? I have gotten 3 different messages from Google in my Webmaster Tools alerting me to an increase in 404s. Should I definitely go to the effort of moving servers and fixing the 404s or is it more of a guideline from Google and not that big a deal in terms of rankings?
Your help as always is very much appreciated.
