Intermittent Network Issue on Blackberry Enterprise Server

Issue:

Users were unable to send/receive the emails from Blackberry Devices.

Solution:

To fix the issue I have done manual fail over to the other instance. After the movement users were able to send/receive the emails from Blackberry Devices.

While troubleshooting the server instance in which there is intermittent network issue, there are multiple NETLOGON events with event id 5719

This issue was related to DNS. To fix the issue, you need to run two command as mentioned below

ipconfig /flushdns
ipconfig /registerdns
