    on my server 2008 r2 (that is a VM)
    it is the DNS server
    preferred dns server: itself
    alternate dns server: ISP dns server

    it is also the DHCP server. so the dhcp server is giving out the same above settings to the workstations.

    is this a bad idea ? will it cause problems ?

    Dont put your ISP dns in your NIC settings. put them in your DNS forwarders

    so i should leave the "alternate dns server" blank ?
    that is what i was thinking would be best.
    i was wondering if putting the ISP dns as the alternate would work as if i put the isp dns as a forward.

    If you only have one internal DNS server, then leave the alternate blank - yes

    Yup...a DC looks at itself for DNS (if you have multiple DCs...you can fill those in)..but we're talking about 1 server here, so just itself. And DHCP hands out the DCs IP for DNS to clients.

    Learn where to do the DNS forwarding in MMC of the DNS object. It is in there where you put the outside DNS servers..such as your ISPs...or better yet, something safer like OpenDNS or ComodoDNS or some other safer DNS service of your choice which helps in content filtering and/or protection against malware.
