Windows Event Viewer not logging CRM alerts and errors

You may face an issue while trying to get information, errors and alerts from your Dynamics CRM / 365 CE instance in the Windows Event Viewer. If so, keep in mind it can be due security settings on your Windows Server enviroment.

Event Viewer on CRM servers can be not logging CRM alerts and errors due a security setting that is denying CRM platform to write on it. Because of this it could be passing the impression of CRM servers and application were running well, as no errors were logged.

Some changes on this security setting can be made, as follow:

- need to change the registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ Eventlog\Application\CustomSD. Tip: You can copy this key to CustomSDold, to keep the history of previous settings / old value.

- change this key, adding in the end the values: (A;;0x0002;;;AU) (A;;0x3;;;AU).

- change the registry key HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/EventLog/ Application/RestrictGuestAccess to 0.

After implemented this procedure, Event Viewer will start logging CRM warnings and errors.
