missing records in DNS - ADSPI_DNS policies

[Michael Kissinger]

Hi guys,
we've got OVO/W version 7.20.100.
We are using Active Directory SPI for DNS monitoring. The ADSPI-DNS_* policies reports many major and warning alarms, like ADSPI-DNS_GC_A_Chk: Domain controller osldc01.eu.boehringer.com is missing the following records in DNS: gc._msdcs.boehringer.com.
That's confusing for us, because osldc01 resides in eu.boehringer.com domain and not in the root-domain 'boehringer.com'. Therefore it forword the DNS request to one of our root DNS servers.
There are a lot of other events regarding DNS that we could not understand. Its like _kerberos._tcp.dc._msdcs.eu.boehringer.com, _ldap._tcp.gc._msdcs.boehringer.com, _ldap._tcp.gc._msdcs.boehringer.com,_gc._tcp.boehringer.com,_ldap._tcp.Burlington._sites.gc._msdcs.boehringer.com,_gc._tcp.Burlington._sites.boehringer.com
Any idea what this means?
Thanks. Mikel
