When I try using nslookup this is what I get "Can't find name for address xxx.xxx.xxx.xxx.  DNS request timed-out."  I'm trying to configure the correct dns settings for each client.

Also use the DHCP setting to push the pertinent DNS servers to clients if DHCP option is available. This will help you avoid setting the DNS servers settings on NIC for each client.

Yes. Do you not have an existing DHCP roles ?

The DHCP server have scopes for each subnet and within each scope you can define which DNS settings should be pushed down to the clients requesting the IPs.

The DHCP project should include the network team.

I'm not sure.  There was a consultant before me that would work on the server so I'm not sure what he has done to it but we were having problems with network connectivity lately so I'm looking into it now.

Sure, depending on the size (number of users), the DHCP is your best in order to ensure that DNS settings are properly configured on all clients.

I doubt if you already don't have a DHCP server.
