When I try to join my new server to my existing domain I get the following error:

"An attempt to resolve the DNS name of a DC in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resove DNS names in the target domain."

I have tried all of the following already:

Successfully pinged the domain controller. Ping the new server from the domain controller by IP address and by DNS name. Ping the DC server from the new server by IP address and by DNS name. Changed the network to DHCP (it was originally static). No joy as static or DHCP. Turned off all firewall settings. Added the domain name to 'hosts' file. Added the server name of the primary domain controller to the 'hosts' file in the new server.

Any ideas? Thanks in advance for any help! Jim

Update: With help from J. Brian Kelly (Thanks) I have managed to narrow down the problem to a DNS issue. Specifically, UDP/53 packets are being sent (they are seen in Network Monitor), but are not getting to the DNS server. But, I do not yet know why.

Update: The quested output from IPCONFIG for the HyperV host and the virtual machine.
