I am getting an error message in Netscape that says that "the certificate that the site 'my.domain.com/' has presented does not contain the correct site name. It is possible, though unlikely, that someone may be trying to intercept your communication with this site. If you suspect the certificate shown below does not belong to the site you are connecting with, please cancel the connection and notify the site administrator." What does this mean?

When you generated the certificate, it is the 'Server Host Name' in question (which is actually the Common Name field of the cert). Make sure you put the exact server name as it will show in the URL or you will get this error. Also once you've sorted out this problem, you'll start to see the message 'my.domain.com/' is a site that uses encryption to protect transmitted information. However, Netscape does not recognize the authority who signed its certificate. To fix this, you'll need to get a 'trusted' certificate from someone like Thawte or Verisign.
