Re-install your domain controller operating system and reconfigure the domain name to something like this (e.g.. testlan.com) , Configure active directory, dns etc. again.
Disable the nic used for Internet connection ( 192.168.2.114) during the re-installation of the AD domain controller. The second nic will be used for the re-installation with the 10.1.1.1 ip. Name your virtual domain controller vm (something like win2k3svr)
After the re-installation, an ipconfig should show the host name: win2k3svr and the ip address information. Then try to join your workstation to the new domain just created.
