How to resolve the communication error 12007 (with Event ID 1014) occurring in the event logs?
Let us consider the below use case to resolve the communication error:
Problem Statement:
Error 12007 (Unable to resolve the server name) thrown by the agent due to DNS client error, displaying the Event ID 1014 in the event logs.
Problem Analysis:
The user is using Active Directory's DNS server that is configured to the server's network interface. Thus, during a network communication, the external domains including plus.site24x7.com, plus2.site24x7.com, and plus3.site24x7.com are resolved using this DNS server.
Note: By default, the domain resolver time-out of the DNS server is 3 seconds.
Troubleshooting Steps:
-
Go to the device where the DNS server is running and open the DNS Manager using the command
dnsmgmt.msc
-
Select the DNS Server which is configured in the device's network interface
-
Select tab " Forwarders " and click on Edit
-
Across the option " Number of seconds before forward queries time out ", change the time-out to 15 seconds
-
Click OK to save the changes
