Hi,

I have a problem to perform LDAP queries. The query is carried out
JAVA through an LDAP URL and if it works sometimes and sometimes not.
There are 2 DC in the organization and there is a DNS that is not DC. (DC1,
DC2 and DNS2)

Investigating, I find that when not working is because the suffix
domain (company.local) resolves the DNS is not DC, and the query fails. A
ping to company.local resolves as DC1, DC2 and DNS2

Is there a way to set the DNS value to always be the same
whoever solves server DC1 or DC2?

Any idea?

thanks and best regards

Are you saying you have a dns server that points to a resolved dns name that
isn't a DC? If that is so then you have not properly configured your
namespace for AD. For me your explanation isn't clear enough to fully
understand the problem you have and then be able to provide you with an
answer.

The organization have a DC with DNS, and other DC. In addition, there is
another DNS that isnĀ“t a DC.

I understand that if all DNS were DC there would be no problem.

My question is whether there is any way that when querying LDAP can force
the company.local domain name is resolved by the same IP?

Thanks
