Netlogon Event ID 5719, this event ID occurs in all Microsoft Operating System machines. Netlogon 5719 occurs due to many reasons and we need to be careful while fixing this issue. Most of the time it occurs due to intermittent network problems.

If this occurs on Client Machines:

1. Check the NIC drivers and keep them upto date.
2. Check domain controller's NIC drivers and upgrade them as well.
3. From client access domain controller's shares.
4. No access of shares then unjoin and rejoin clinet machine to domain.

If this occurs on Servers:

1. Check NIC drivers and upgrade them.
2. Check domain controller's NIC drivers and upgrade them as well.
3. If upgrading NIC drivers doesn't fix issue, uninstall NIC completely and reboot server.
4. Check Secure channel status using nltest /sc_query:domain.local (NLTEST)
5. If secure channel is broken, unjoin and rejoin server to domain.
6. If it's a Domain Controller, take system state backup and demote and promote.

Note:- If it's an Exchange server, take full backup. Disable all Exchange related Services and reboot the server, after reboot you can try updating NIC drivers or uninstalling NIC card or unjoin and rejoin to domain.
