No, it's not true. Whether a bot or a person is accessing your site they all go through the webserver software (Apache for example) which accesses the robots.txt file in the same way for every request. It will either always be able to read it, or never. If it's never then something's probably configured wrong.

Can search engine robots read file with permission 640?
I am trying to add a static DNS forward under DNS in Windows Server 2008 R2 however I can't figure it out.

Under Server 2003 you simply add an DNS domain name with it's forwarder IP list.

However under Server 2008 you only seem to be able to add IP addresses. The IP's I enter will not resolve/validate, plus it doesn't appear to allow you to enter a matching DNS domain name.

Can someone please help?
