DNS issue in Windows server 2012

Hello everyone,

 please I want to ask you about issue with DNS in Windows server 2012. In my domain I have got record such as test.mydomain.eu. This record in past direct to local IP address 192.168.5.10. And now I want to change this record to direct external IP address. All is ok, all is working, DNS server restarted. But after few minutes maybe 30 minutes record automatic change to last local IP. I tried it few times with same result.

Do you know where is the problem ? There is any cashe of DNS server or someting else ?

Thank you for advice

Do you have just one server with DNS service running? Or are there more than that one? Are they sychronized?
