New web site search engine url has w.deanindustrial.com and ww.deanindustrial.com

We updated our web site from Frontpage to Joomla. The main search engines (Google, Yahoo & Bing) are listing url's w.deanindustrial.com and ww.deanindustrial.com, these go to 404/401. I have tried in Google to remove the w or ww web sites, it requires downloading a HTML verification file & upload to the w or ww web sites. Since these web sites do not exist, not sure how to proceed.

I contacted our Joomla developer, they requested I contact our ISP who will fix this problem. The ISP referred me to the following sites:

support.google.com/webmasters/answer/1663419?hl=en

bing.com/webmaster/help/bing-content-removal-tool-cb6c294d

help.yahoo.com/kb/SLN4530.html

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Tell your ISP to create w and ww as aliases ("cname records") for www - that will kill the 404's.

Once that is done, you can proceed with the instructions in the three links they gave you.

Another good question to ask is how the 'w' and 'ww' subdomains came to be indexed originally.
deanindAuthor Commented:
Thanks, it appears the web developer team created the aliases and they may have corrected the same. I will monitor the situation. Thanks for your comments, I felt like the "man in the middle".
