Description:
Process STORE.EXE (PID=4972). Exchange Active Directory Provider is unable to connect to the Domain Controller EAI-DC2.eafg.local although its service location (SRV) resource record was found in the DNS
The query was for the SRV record for _ldap._tcp.dc._msdcs.eafg.local
The following domain controllers were identified by the query:
eai-dc2.eafg.local
eai-dc-01.eafg.local
eafg1.eafg.local
eai-dc-02.eafg.local
eai-pdc.eafg.local
Common causes of this error include:
- Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses.
- Domain controllers registered in DNS are not connected to the network or are not running.

Hi,
What's the symptom for your Exchange server after appearing the error message? Did the Outlook client connect Exchange server being affected?
Thanks
