I've got a PC that I only want the user to access a limited number of web sites. I edited the c:\winnt\system32\drivers\
etc\hosts file as follows (example):
then I took out the DNS server addresses on tcp/ip
this worked on one PC but not on another. It works on some web sites, but not on others (for example, I can't get it to work on microsoft.com, but can get it to work with some insurance-related web sites. I know this is the right IP address, so why doesn't it work consistently?
