You need to consult your OS's documentation to see how DNS failover should be set up. That is, if your client attempts to contact a particular DNS server running on a DC and it doesn't answer, it goes to the next DC DNS server without any real delay.
I have checked on a few desktops in the office and all of them have both DCs as their DNS servers.
When I test with a command prompt and nslookup for either the top-level domain or any server within the domain they give the correct IP addresses - both using forward and reverse DNS checking.
I have followed through the Samba Wiki pages of Troubleshooting and all the desktops pass the DNS and SRV tests etc.
What else can I check or test?!
