[QUOTE="vanza, post: 907925, member: 121284"] hi guys, One of the student/education network that I manage is basically spliced into 2subnets: 10.1.2.1 (Mac OS X Server with 120 iMacs) 10.1.1.1 (Windows Server 2003 with 45 Win XPPro w/stations) ADSL2+ Internet connection gateway is via modem/router with both the above Servers doing DHCP/ActiveDirectory/Group Policies/Open Directory/DNS fwd etc. etc. for their respective client machines. Despite using openDNS ([url=http://www.opendns.com]OpenDNS | Providing A Safer And Faster Internet[/url]) for Internet filter, I'm still facing huge bandwidth usage from the students...average of ~6GB a day Mon-Fri. Almost every month, the ISP throttles the speed mid-month due to usage going over-quota. I've tried (in a test environment) to completely disallow students access to Windows machines and found that there's not much difference in usage however when I completely disallow students using Macs, I see significant drop in Internet usage. Although openDNS works as filter for both networks but am not sure if iTunes/streaming etc is being affected by filter hence students on iMacs are being able to spike Internet usage. Are there any ways to find from Mac X Server how to address this issue? block iTunes? how? Any suggestions would be much appreciated. thnx, Eddie [/QUOTE]
