There are also a few 900, 902, 903 events. Any ideas what is happening? Everything seems to be running fine.

Hi,
The event 4625 indicates a computer account failed to logon. You could run NLTEST /SC_RESET:domain-name command with administrative credentials to check domain’s health.

Do you have accounts that are set up to be locked out after failed login attempts?
Was a service account password changed?

This Event is usually caused by a stale hidden credential. Try this from the system giving the error:
From a command prompt run: psexec -i -s -d cmd.exe
From the new DOS window run: rundll32 keymgr.dll,KRShowKeyMgr
Remove any items that appear in the list of Stored User Names and Passwords. Restart the computer.Wednesday, October 7, 2015 9:05 PM
