"There are certain CAD modules that rely upon reverse DNS lookups. If this feature is turned off on the machines running CAD services, there will be a loss of some functionality and errors will be generated and logged".
Do you know which CAD modules and functionality rely upon DNS?
Is the operation of CAD totally or partially compromised? How?
I had a customer set up without any DNS entries. Everything worked fine until I tried to set up agent email. Agent email relies on DNS to resolve the hostname/ip of the client, and would not work.
As it happened, the clients were on a few citrix servers, so I asked TAC to add entries for the citrix servers to the hosts file of the UCCX server. This was a temporary work-around (which is not officially supported), and I later set up DNS entries.
Remember, if you change dns entries after the initial setup, your license mac will change and the license will need to be rehosted.
