sub : deny access to certain websites and instant messengers like msn, icq etc. we use nt2000 small business server edition and have got isa server installed in the main server. now what we have done is. (source-isaserver.org & ms technet) 1) configured the 'destination set' 2) configured the 'site and content rule' 3) installed and configured 'firewall client' on one of the client machines. still its the same, meaning its not blocking those sites. ne idea ??
