Question : Hosts file resolution does not work

I have Active Directory network and I am using hosts files to translate some websites to another IP addresses. But one PC stopped using hosts file for resolution. I can type something to this file and it is not translated as I typed. It was working at past.
Where can be problem?

Answer : Hosts file resolution does not work

Try to set up a new host file with *one* entry only, and see if that is used. If so, either the length or format is the issue.
