A few months ago, I was asked a question about how to assign a connection specific DNS Suffix to a NIC which was different from the Active Directory Domain. For example, the AD Domain was contoso.com, but they wanted to be able to assign a DNS suffix of cluster.contoso.com. If the Fully Qualified Domain Name (FQDN) of cluster.contoso.com was specified as a DHCP scope option (015 DNS Domain Name), then the installation would fail when the nodes attempted to join an Active Directory Domain that did not exist.
This scenario would only arise for clusters which are configured with network topology 2 or 4, where all the compute nodes have a connection to the enterprise LAN as well as to the private one. Otherwise, this would not be an issue, because the compute nodes would only be connected to the private network and would not be accessable from the rest of the enterprise and therefore would not have DNS entries.
After some searching, I determined that a good work around would be to add a new domain to the contoso.com DNS Forward Lookup Zone. The steps to implement this solution are as follows:
