[ISSUE 3]
Problem Description:
================
From ExBPA report, the Exchange server cannot access port 389 of a domain controller named studc1.
There are one parent domain and three child domains in this organization. The issue only occurs within one child domain.
Cause:
================
Based on the network trace, we found that that IP address of the domain controller does not map to the correct FQDN of the domain controller.
After further investigation, we found that there is an incorrect A record for this domain controller in the DNS server of the root domain.
Resolution:
================
Remove the incorrect DNS A record and add a correct one.
