I know mappings in the hosts file are checked before DNS. Is this true even in an Active Directory environment? What about if you use a proxy server definedin your IE settings?
Thanks

yes the host file is always checked first, regarless if the PC is in a omain or not, or if there is a proxy server involved.  Why do you ask?

We have a user that has circumvented the proxy server and is playing games on an online site. Since the proxy server is maintained by another entity, it costs us money everytime we have to notify them and tell them to adjust something.

We are looking to place some settings in her hosts file like this

127.0.0.1                   game_site_she_is_visiting.com


We obviously have access to the C$, so I'm going to try this remotely.

Thanks

I´m not sure, what your're aiming at with the last question, but Yes, the host file is checked before DNS, AD or no AD. One of my customers had problems with the local domain name being the same as the domain name supplied by their ISP. As a result the computer was searching for the e-mail server in the local domain, instead of the ISP. I did a quick and dirty solution by adding the e-mail servers adress in the host file. It worked fine. I later added a static entry in the DNS instead, but thats an other story.

I heard that sometimes, when you enter things in the hosts file, it may not work if you have a proxy server.  Because the browser is configured to use the proxy server etc..
I wonder if the BYPASS FOR LOCAL ADDRESSES would work in this case?
thanks guys

if you enter 127.0.0.1                   game_site_she_is_visiting.com in the host file it should solve your problem. But all you have to do is test it out on your computer to be 100% sure.

Add:
127.0.0.1                   game_site_she_is_visiting.com
in the host file of your computer and then try to access the site and see if you can access it or not.
