Cleansing Old DNS Entries after AD Takeover

UCS - Univention Corporate Server

Hey, hope you are doing all right.

I was testing today my local DNS setup and discovered some leftovers of an AD Takeover completed long time ago and I am wondering if there is any way to get this cleansed?

I looked into the corresponding knots in LDAP, but I am not finding any reference to those old servers (old: tmp.local.domain ucs.local.domain).

Is there a possibility to get this cleansed?

cmd
nslookup
> _kerberos._tcp.dc._msdcs.local.domain
Server: dc.local.domain
Address: 192.168.88.88

_kerberos._tcp.dc._msdcs.local.domain       SRV service location:
          priority = 0
          weight   = 100
          port     = 88
srv hostname = dc.local.domain
_msdcs.local.domain  nameserver =  dc.local.domain
_msdcs.local.domain  nameserver = ucs.local.domain
_msdcs.local.domain  nameserver = tmp.local.domain

cmd
nslookup
> _kerberos._tcp.default-first-site-name._sites.dc._msdcs.local.domain 192.168.88.88
Server:  [192.168.88.88]
Address:  192.168.88.88

_kerberos._tcp.default-first-site-name._sites.dc._msdcs.local.domain SRV service location:
          priority       = 0
          weight         = 100
          port           = 88
          svr hostname   = dc.local.domain
_msdcs.local.domain  nameserver = tmp.local.domain
_msdcs.local.domain  nameserver = ucs.local.domain
_msdcs.local.domain  nameserver = dc.local.domain
dc.local.domain     internet address = 192.168.88.88

Was there a fix here, I have used Registry to remove old dns entries, still see them after reboot and samba/bind9 restart.
