While looking through my Windows Server 2003 AD DC's DNS management I noticed Kerberos and Ldap references to and old DC that has since crashed and been replaced but is no longer functioning as a DC will removing these references to the old machine cause any problems?
Basically it shows here:
Forward Lookup Zones
domain.com
_msdcs
dc
_sites
default-first-site-name
_tcp
_kerberos Current Primary AD DC Windows Server 2003 sp2
_kerberos Current Second AD DC Windows Server 2008 r2
_kerberos Old sec DC Windows Server 2003 sp2
_ldap Current Pri AD DC
_ldap Current Sec AD DC
_ldap Old sec DC
This also shows in the domains, sites, TCP, and UDP under the _msdcs tree.
