I want to use this techique to block against adservers ect.. I don't want to install 3rd party programs and stuff if it can be done mauallly in 2K. I heard it can be done in XP somehow, but how do i do it in Win2K? Oh.. if you know, for that matter is it possible in NT4? Win2K SP2, IE5.5 SP2, NT4, IE6 Cheers,

Then, just put in the domain names that you want to "block" and the IP that you want the requests to go to (like 127.0.0.1). The hosts file will be scanned first before your DNS servers, so anything listed on here will be resolved from this file rather than an outside source. To test this, enter your domain name and IP that you want to block, and then bring up the command prompt. From there, type "ipconfig /flushdns" and that will flush out any DNS mappings that are already in the localhost. Then, ping the domain name that you listed.

Say i want to block anything and everything at the domain www.yahoo.com , including www.yahoo.com/subcategories/ What would be the snippet of text i would put in the hosts file? Thanks heaps Clutch, Cheers.

Any tips on how this would affect browsing the net would be greatly appreciated, Thanks Guys. Cheers,

As for browsing, it should speed it up a slight amount as your system will not only be saved the time of resolving those network names, but it will also save the system time in downloading anything from those sites.
