One possible solution, if you are going to use ZT... Is you will need to install ZT on at least one domain controller...
On this domain controller, you should:
- Set the ZT Adapter to use DHCP for the IPv4 Address and DNS settings, and the OK back out.
- Set the ZT Adapter to not register in DNS
- Check DNS and remove the ZT Adapter IP address.
On the Client Machines, you should:
- Set the ZT Adapter to use DHCP for the IPv4 Address and DNS settings, and the OK back out.
- Set the ZT Adapter to not register in DNS
- Check DNS and remove the ZT Adapter IP address.
4) Modify the C:\Windows\system32\drivers\etc\hosts file to add an entry for the DC and its ZT IP address.
Depending on the number of clients you have, that seems to be a feasible set of instructions.
