Guys,
PTR records have no effect on "name resolution".
You do not need to setup or configure reverse lookup zones for forward
lookups to work.

Austin,


Wer're not talking about Forward Lookups. We're talking about a reverse PTR
record in the reverse zone. The SPN record for the domain controlller is
used by the SPNEgo and is based on the PTR for the DC. If this is missing,
you will get SPNEGO and LSASRV errors, respectively 40960's and 40961's.

Back to the original poster, Yakob:
You also mentioned EventID 10, Source=Kerberos. That is usually due to some
sort of firewall blocking traffic, specifically UDP port 88 Kerberos
traffic. Is the firewall turned on? Is there an AV software present that may
be blocking traffic?
