If you copy your DNS entry out of the device in PRTG e.g. myserver.dns.local, logon to your probe server via RDP then issue the command:
ping myserver.dns.local
if it still says the old IP address, thats why.
.
As for what you can do to correct it, one of these will probably fix it:
1 you could try RDPing onto the server, run a command prompt and issue the command:
ipconfig /registerdns
on the server itself (then wait a while until local DNS expires on the probe).
or
2 Logon to your domain controller, open DNS, find the entry in DNS and update the IP address (then wait a while until local DNS expires on the probe).
I've have made some assumptions here, but hopefully this will get you on the right path.
