My unpublished registered Com names used in the Web. How to prevent it?
I have several registered Com names which I have not put on the web. However I have just found out they are on the web advertising business and web pages for others. How can this be?
They are advertising with my com names at my expense and without my authorisation.
I know that if I go into the area of my coms management I can change something to stop it but I don’t know how to do it.
Can sombody please help me with this. I am really very upset with this blatant and unauthorised use of my com names.
Any help will be greatly appreciated.
The domain are with dnbuy.com and the people who are using them are Sedo, I think
All of my domain names are paid on a yearly basis. They are not free domains.
I do I put them all together in one page to point to them?

contact your domain name host(s), since they are the people responsible for what appears at the address until you at the very least place your own index.htm file on the domain.
no-one can give you specific instructions for altering this manually, since there are thousands of domain name hosting companies and each one normally offers two or three different interfaces for users to manage their domains – if you add additional details of who the domain name hoster is and which software you/they are using we probably can.
EDIT:
if you genuinely believe the domain(s) have been stolen, you should do a ‘whois’ on the domain(s) using this:
http://www.whois.net/
it will return who legally owns the domain, and should have either your personal details or the details of dnbuy.com.
either way, dnbuy.com will be best placed to tell you exactly how/why the unused domain(s) have an advertising page on them. unfortunately they have no email address listed on the contact page so you may need to call them:
http://dnbuy.com/contact.html
If these are free names, and they are parked, there is nothing you can do about it. If you pay for them find a site which will allow you to park them, or point them all at one hosting site with a single page saying This domain name is held here or similar. This way you have full control on them
