Hi, all.
I've recently had to migrate my SBS 2008 system to a different subnet, and all went fairly well except that in DNS, the A record for the server keeps reverting back to its old IP address. I can create a new A record for the server and delete the old (incorrect) A record, but after a while the address for the entry reverts back to the old IP. And in the DNS Manager it has a timestamp, rather than "static". I've looked everywhere and can't find the old address, but it's sneaking in from somewhere.
I've checked all DNS zones and removed any old IPs I've found in the Nameservers tabs. I've checked RRAS and it appears to be configured correctly (it shows the new IP subnet only, not the old one).
Any thoughts as to what I could check to find the source of this old IP showing up in DNS?
Many thanks!
