I have several computers that are purely for internet access only. Some are kiosks and some have full internet access. I would like to use AD to have better granularity on group policies. Do I need cals for these computers if they only use the server for AD, dns and dhcp? There are no other services used. I found this vague quote from Microsoft's website concerning cals: "..Windows CALs are required when accessing or using the server software." http://www.microsoft.com/resources/sam/lic...003_server.mspx Is AD considered 'server software'? Thanks, Nick
