DNS old records

Hallo, as we have some weired dns problems, i tried to find out where they come from. Following is our settup:

2DCs with AD integrated DNS-Zones

Forward-Lookupzone on activeDC1

 +_msdcs.abcdomain.local -> seems okay

 + _sites.abcdomain.local -> seems okay

 + _tcp.abcdomain.local -> seems okay

 + _udp.abcdomain.local -> seems okay

 + abcdomain.local

      (same as parent folder) Host (A) 0.0.0.0 Static ---> this entry seems very weired? Wenn I make a nslookup abcdomain.local i get the two Domain Controller and 0.0.0.0. Can I saftly delete this entry, whereever it came from?

      + _msdcs --->  (same as parent folder) Nameserver olderservername static ---> I think I slould delete this old entry and only leave the second one pointing to itself. Or do I also Need to configure our second DC as nameserver in this Delegation?

                      --->  (same as parent folder) Nameserver activeDC1 static

       + _sites --->  (same as parent folder) Nameserver olderservername static ---> I think I slould delete this old entry and only leave the second one pointing to itself. Or do I also Need to configure our second DC as nameserver in this Delegation?

                      --->  (same as parent folder) Nameserver activeDC1 static

     + _tcp --->  (same as parent folder) Nameserver olderservername static ---> I think I slould delete this old entry and only leave the second one pointing to itself. Or do I also Need to configure our second DC as nameserver in this Delegation?

                      --->  (same as parent folder) Nameserver activeDC1 static

     + _udp --->  (same as parent folder) Nameserver olderservername static ---> I think I slould delete this old entry and only leave the second one pointing to itself. Or do I also Need to configure our second DC as nameserver in this Delegation?

                      --->  (same as parent folder) Nameserver activeDC1 static

     + DomainDnsZones --->  (same as parent folder) Host (A) wrongIPentry olddate ---> Can I safety delete this old entry whereever it comes from.

                      --->  (same as parent folder) Host (A) IP-DC1 dynamic

                      --->  (same as parent folder) Host (A) IP-DC2 dynamic

    + ForestDnsZones --->  (same as parent folder) Host (A) wrong IP olddate --->Can I safety delete this old entry whereever it comes from.

                      --->  (same as parent folder) Host (A) IP-DC1 dynamic

                      --->  (same as parent folder) Host (A) IP-DC2 dynamic

The rest of the configuration seems okay. I bet these wrong entries are from our Domain upgrade 2003-2008 but already a few years old. Our main Problem is when connecting to Shares via dns Name. Sometimes you are able to browse normally but very often browsing is very very slow and takes a long time to show the files. It's like Name Resolution is having timeouts. So we use netbios at the moment to overcome the problem...Hopefully you can give me advice about the correct DNS entries. Regards
