In Windows Server, which command line command can you use to determine your logon server?

• ipconfig /logonserver
• find /logon_server
• echo %logonserver%

EXPLANATION

the DC you use as the logonserver may be one of several in the domain. Your PC will determine the “best” DC to use based on how your AD sites are setup.
If you are in a situation where you need to discover which DC the PC you're using has used to logon you can do this using the echo %logonserver% cmd.
