New AD SRV records not being added to DNS

[#1]

Although we already have a dozen of AD servers with SRV records in the AD zones of Infoblox it seems the records for a new AD server don't get added to the zones.

In the log we do see that the updates are allowed :

client 123.123.123.123#54385: updating zone _msdcs.mydomain.com/IN: adding an RR at _ldap._tcp.dc._msdcs.mydomain.com SRV 0 100 389 NEWAD.mydomain.com.

Yet in the _msdcs.mydomain.com zone the SRV record is nowhere to be found. Same goes for the SRV records that should be in the other AD zones (_tcp.mydomain.com, _sites.mydomain.com, ...)

The only record that has been added to the _msdcs_mydomain.com zone is a CNAME (that looks like some unique ID).

Don't know if it is a software problem on the Grid or a configuration issue.

The older AD servers have been in DNS for several years. Now we are running version 8.0.3.

ran a search in global search--> advanced for ' _ldap._tcp.dc._msdcs.mydomain.com' this would give an idea if it is there in the DB. Also, comb the sys logs to find if it was deleted later.

Can you show a screenshot of the supposed missing records? I find that the most typical mistake people make is to navigate into the subzone via the tab, but forget to change into the record view.
