Active Directory is reliant on DNS, not NetBIOS naming (as provided by LMHosts).<br />
<br />
You should not be using external name servers in client configuration, no matter what that gives you. I take it you cannot setup another name server within your network to deal with this blocking?<br />

Well, the goal of doing that is to direct some workstations to one public DNS server and other workstations to other dns servers. &nbsp;Workstations A will get their internet domain name resolution from OPenDNS which is setup to filter websites and Workstations B will get their internet domain name resolutions from another DNS supplier (from the ISP). &nbsp;Workstations A&amp;B are on same 2003 domain. &nbsp;2003 domain controller is setup to forward internet DNS requests.

I think you'll have to look outside of DNS for a solution I'm afraid. Setting OpenDNS up as a primary DNS server on a client will only hinder their ability to act as a member of the domain.<br />
<br />
If you could set up a second internal DNS server then it could be made to work well enough, but I suspect that's a bit too much of a cost?<br />

Yeah setting up another physical dns server is not something that is cost effective in this scenario. &nbsp; My understanding of an lmhost file was that a workstation would check the local lmhost file to resolve a name before going out to a dns server. &nbsp;Any other options???

<div>
You think lowering the timeout would help. These workstations don't access many services on network.

<div>
<br />
No idea how you would do that, but I can't advise it at all. It breaks client authentication because they will almost certainly fail when it gets to the NetBIOS stage (despite the entry you've added to LMHosts).<br />

Hi, I am trying to filter internet access by using open dns. &nbsp;Thing is i want to limit it's use to only some workstations on the network. &nbsp;I have a DHCP service running on the DC (w2k3 SBS) that has reservation for the workstations i need filtered. &nbsp;The reservation states that the workstations in question should use Open DNS as their primary DNS server. &nbsp;As it stands now login times are slow and some resources such as mapped drives are not mapped. &nbsp;So i decided to implement a LMHost file and specify the server name. &nbsp;Here is the line i am using in the lmhost file (that i have stripped of .sam name):<br />
<br />
192.168.1.3 &nbsp; &nbsp; server &nbsp; &nbsp; &nbsp; &nbsp; #PRE #DOM:xxx.local &nbsp;#DC du groupe rseau<br />
<br />
Even with this it doesn't speed up logins. &nbsp;Note: NIC properties are setup by default (i.e. Wins enable LMhost lookups)<br />

I am not using a host file.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
