DNS error 404, 407,408 on Server 2008 R2

Question

Trying migrate an old Server 2003 DC to 2008 DC.  I ran adprep, forest etc on the old domain controller and everything was successful.
On the first domain controller (Server 2003)  the 1^st NIC card has an IP of 192.168.1.2 subnet of 255.255.255.0, gateway of 192.168.1.1 (Router) and DNS of 192.168.1.10. 
On the 2^nd card on the same server, the IP is 192.168.1.10, subnet of 255.255.255.0, gateway of 192.168.1.1 and DNS 192.168.1.10. 
When I first tried to promote active directory I received an RPC error. 
I noticed that RRAS was installed on the old domain controller and removed it since it is no longer needed. 
After removing, Active directory successfully transferred and replicated. 
I then went to Transfer the FSMO roles and it transferred successfully. 
After rebooting the 2008 server I now get a DNS error “The DNS server could not open socket for address 192.168.1.9.”, “The DNS server could not bind a Transmission Control Protocol (TCP) socket
to address 192.168.1.9”. “The DNS server could not bind a User Datagram Protocol (UDP) socket to 192.168.1.9.” 
These errors are 404, 407 and 408.  On other programs are running on port 53. 
On active directory I get an event error Event ID2092 ” This server is the owner of the following FSMO role, but does not consider it valid.”
If I shut down the old 2003 domain controller active directory does not work. 
I cannot connect to Active directory sites and services, users and computers etc. 
The old domain controller resumed the primary FSMO roles. 
What can I do to correct this problem?

Hi,
Holding two NICs/IP address is not recommanded on DCs, Mr. Ace got a blog on this, see:
Multihomed DCs with DNS, RRAS, and/or PPPoE adapters
http://msmvps.com/blogs/acefekay/archive/2009/08/17/multihomed-dcs-with-dns-rras-and-or-pppoe-adapters.aspx
If two IP addresses on the old DC are no longer needed, please try to configure into one IP address. We may consider to transfer the FSMO back and once the environment is clean, we can then have all the FSMOs on the new DC.
Please run DCDiag, NetDiag and Repadmin to check the health of the DCs and the replication and
Ipconfig /all for the two DCs, If possible, please upload the output into skydrive and post the link here.
In addition, please check if the following articles could help:
Event ID 408 — DNS Server Configuration
Event ID 404 — DNS Server Service Status
Best regards
Michael
