I question the rationale for this.? Anybody can use a free network scanner and in less than 1 minute know what is where regardless of hostname or IP.? Chaning hostnames and IPs really doesn't gain them anything.? It just sounds like they don't have enough to do in the day.? Using authentication on the processors and changing the password every couple of months, that I can understand.? On another note, do the Crestron systems need to be on their internal network?? Can they create an isolated dedicated VLAN for the Crestron systems that no one has access to?? We have had to do this to appease the IT departments before.? If they insist on doing this, which they probably will, this will be a reoccurring fee for them and for you.? That might change their mind.
