UpGrade Isilon DNS

Good evening!
We are using UpGrade from our Isilon and we would like to keep the same sharing configuration, IP of the new Isilon that will be.
When I make these settings on our DNS server, I can communicate via ping by IP and Hostname. RoundRobin works normally, but when it tries to access or share via \\, it gives an error, it says that the is not correct.
Do I have to do some cleaning on our DNS server for any entries that have something to do? I cleared the cache and the problem still persists...

If anyone can help me, I'd appreciate it!
