View source for Logon,logoff,locking in the event log

==Purpose==
To record my notes on logging events related to logon, logoff, and locking of Windows systems on a domain.

==Enabling Printer Auditing via GPO==
It appears that to enable print logging, using the built in logging function, you have to edit the registry to
#Enable the log<ref>https://social.technet.microsoft.com/Forums/windowsserver/en-US/8e7399f6-ffdc-48d6-927b-f0beebd4c7f0/enabling-print-history-through-group-policy?forum=winserverprint</ref>
#Tell the system the log exists.<ref>https://support.netaphor.com/index.php?/article/AA-00574/0/Enabling-Print-Logging-on-Windows-Server-2008-R2-and-Newer-Print-Servers.html</ref>
<br>
<br>
The following edits and additions are needed
#Update the following to 1 (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \Windows\CurrentVersion\WINEVT\Channels \Microsoft-Windows-PrintService/Operational, entry Enabled)
#Create the following key (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Microsoft-Windows-PrintService/Operational)
<br>
<br>
Windows comes with an operational entry in event viewer for the Microsoft-Windows-PrintService event sub directory. However it gets overwritten with whatever you put into the key that you create. Not sure how it associates the key to print services since every other application has an operational entry, and the location of the key does not seem to corresponding to a particular service.

==Moving Event Log Location==
When moving the log file location, make sure to have proper permissions applied. In my case I wanted the forwarded events to be moved to a mounted drive with more space. As this was done I ran into an issue where the logs would not rotate. I was using a domain controller which prevented me from finding the eventlog security group, which was used for the traditional directory. Xcopy was able to replicate the permissions.<ref>https://arstechnica.com/civis/viewtopic.php?p=24521897</reF>
 xcopy C:\Windows\System32\winevt\Logs E:\Winevt\Logs /O /T

===Collector and Forwarding===
Initial attempt is made using a DC as the collector as it already had spare storage.

*Make sure that if you change the directory in which you store the forwarded log file, that permissions are set to allow full control to both the Local Service and Network Service accounts.
*You do need to enable WinRM on the collector, in this case I am using a DC which already had it configured.
*For machines that will forward security events, make sure the "Network Service" user account is added to the "Evcent Log Readers" security group.<ref>https://social.technet.microsoft.com/Forums/sharepoint/en-US/8434ffb3-1621-4bc5-8311-66d88b215886/how-to-collect-security-logs-using-event-forwarding?forum=winservergen</ref>
