i am getting error messages when i click on http://dexteroustechnologies.com/Khoren/
I think you have a problem with your site installation on your server. I try to access your domain and got the same error message
I moved the thread to server management since I don't know if you use Apache. It does look that your server configuration is wrong. If it was simply a case of not recognising the main page, you would have a list of the files and subfolders there.
Was there a question in that?
Okay, the others have given you the answer: You just don't have a Khoren directory at your site and don't even have a website (no DirectoryIndex at the DocumentRoot). Check with your host for the proper FTP upload address for your website and try again.
