DNS server updated with wrong IPDNS Windows
After migrated Windows 2003 to Windows 2012 R2, the DNS has a A record with wrong IP of the old server name. Checked DHCP and WINS records, both of them are correctly.
srv3 ip is 192.168.1.3 srv1 ip is 192.168.1.5
Sometime the A record of srv1 is correctly and sometime not (IP is srv3’s ip 192.168.1.3 instead of 192.168.1.5). Even through srv1 is static ip.
One of a new domain server (Srv3) has alternate name with old server name (Srv1).
c:\Windows> netdom computername srv3 /ENUMerate All the names of the computer are : srv3.myDomain.local srv1.myDomain.local
Remove the alternate name of srv3
netdom computername srv3 /remove:srv1
