Is their a way to test DNS response times? We are getting certain machines who cant resolve names and it states DNS timed out.

The DNS server (165.x.x.x) that is being used for VPN is having issues again:
c:\>nslookup outlook.com
Server:  .net
Address:  165.x.x.x
 
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to server.net timed-out

DNS is entirely dependent on packet latency, and if the DNS entry is cached on that server or not.

Incidentally - Outlook.com did have an issue late last week (Nov 22, 2013) where Microsoft knocked their name servers offline - causing a major DNS & service outage.

But to answer your question - I've used DNS Benchmark from GRC.

That tool will allow you to benchmark and compare your private DNS server with public servers, etc.

What kinds of problems are you having? Are they using your private DNS server?  If so, is your DNS server using root hints, or is it configured to just forward lookups to another DNS server.

Have you verified the dns setting on client and dc is set correctly.See below link for the same.Best practices for DNS client settings on DC and domain members.
http://abhijitw.wordpress.com/2012/03/03/best-practices-for-dns-client-settings-on-domain-controller/

Also verify the health of DCs by dcdiag /q and repadmin /replsum and post the log if error is reported:http://blogs.technet.com/b/askds/archive/2011/03/22/what-does-dcdiag-actually-do.aspx
