Hi,

Where is the best place to look to see why a dhcp server is failing to update DNS recourds?

the DHCP server is set to update every thing.
it is a member of the DNSproxy groups
the dns proxy group is in the security settings for the forward and reverse zones
the DHCP server has a AD account associated with the DHCP update service for the subnet in question.
the DNS server is set to accept secure and non secure updates

some times (like one in 100 times I see a "successful" reported in the DHCP logs in the DHCP server

32,03/07/16,06:42:23,DNS Update Successful,172.20.0.12,Aarons-Desktop.iahtest.ac.uk,,,0,6,,,,,,,,

but most times I see

31,03/08/16,12:11:31,DNS Update Failed,172.20.0.12,Aarons-Desktop.iahtest.ac.uk,,,0,6,,,,,,,,
30,03/08/16,12:11:31,DNS Update Request,172.20.0.12,Aarons-Desktop.iahtest.ac.uk,,,0,6,,,,,,,,

What I cant find is the logs showing my why this is happening? I want a log that says "update failed due to security/could not find DNS server/etc....

Any thoughts?
