Question : Name resolution is not functional. _ldap._tcp.<mydomain>.co.n<wbr />z. failed on the DNS server

Good morning experts,

I have Windows 2003 SP2 with SBS 2003.

We are getting an error in the event logs, NTDS KCC 1925.  This led me to http://207.46.196.114/windowsserver/en/library/5586ecc0-924b-4f08-800b-9fd6eef056191033.mspx?mfr=true which told me to go to: http://207.46.196.114/windowsserver/en/library/5586ecc0-924b-4f08-800b-9fd6eef056191033.mspx?mfr=true

This page told me to run a basic dns test: dcdiag /test:dns /s:SourceDomainControllerName /DnsBasic

Which I did and here are the results:

The article told me to look for warnings, which there are, but then it goes a bit vague and just tells me to fix them.  Does anyone know how to fix this warning please?  The IP address it is refering to is a secondary DC that has just been promoted.

Thank you

Tom

Answer : Name resolution is not functional. _ldap._tcp.<mydomain>.co.n<wbr />z. failed on the DNS server

you could run the portquery tool to find that .
