i have configured a win2k server asa active directory domain controller which is the root domain of the tree, and is registered in network solutions and pointed to this server. Initially planned the dns server is not connected to any of the clients,and this server is consuming lot of bandwidth, why the server is consuming that much bandwith or is there any thing wrong in the configuration. In addtion to this my dns server is configured as forwarding external dns traffic to the isp dns server.How i can stop the server for consuming internet bandwidth.

If the root DNS servers (i.e., those a Network Solutions) are configured to use your DNS server as the authoritative server for your domain, then ALL DNS queries (both internal and external) for your domain are going first to that server. In addition, if your server is published to the Internet as a DNS server, it may be handling traffic from other domains as well. If that's the way you have set it up (and it looks that way from your description), then it is why there's so much traffic. In this scenario, your DNS forwarders aren't really doing anything for you, since your own DNS server is authoritative for your domain and will cache all other necessary information from the root servers. If you want your ISP's servers to be authoritative for your domain (assuming you have contracted with your ISP to provide this service), then your domain records at Netsol should list the ISP's DNS servers, not yours. Hope this helps!

here in this dns server we are not configured any web site, or aby publishing things, virtually there is no traffic designed for this domain. we have to do it in future, what i am looking can we restrict for this traffic for that i need the solution, don't think that restricting bandwidth for the domain, that won't help, if i configured again ISA in this server then how can be my server will do any thing to my network. I am sorry to say what you have given information for directing to ISP thing, is not my solution.

Please can you give me some more infomation on you setup. I see you are using a ISA server, is this set to send all DNS queries external ot is it Querying the internal DNS first. You see you can set the client to use the ISA as the primary server which will then forward the request external, if this failes then the client with query the internal DNS as long as you set the ISA ip as primary DNS on the client asn the Internal DNS as secondary

Hope this help's, if not can you provide me with a description of what server you have and what they are doing

i am using a dual processor P-III 1Ghz system with 1GB ram, and the os is win2k server having active directory with dns server. While creating upto this level i did't face any problem, while i updated my www.domain.com details(updating A record) then the server is using so much band width, at this juncture i did't put any clients on this machine once it is stabilised then i want to install IAS. Now i want to know why this server is using internet bandwidth what it was doing, i did't put any load, or i did't configured any site so what it is doing, if it is updating dns records from internet root servers then how much time it will do, and how much bandwidth it will use for updating and so things.

my question is if i keep this server for all the clients, this server is using so much of bandwidth then how can this can be useful to my clinets.
