HP Openview event log error
Running on an ancient version of Openview, I see this error on some of my servers:
Event Type: Error Event Source: HPOV-MAA Event Category: None Event ID: 1024 Date: 24/11/2011 Time: 14:01:05 User: N/A Computer: HHG-APP03-B Description: Could not register at the NT Local Security Authority. Actions will not be allowed to switch user accounts. (OpC30-563)
If you're not running the server's agent service under a privileged account you need to ensure that the account has been granted the "Act as part of the operating system" role in Local Security Settings.
Given that the agent normally runs under the SYSTEM account, this isn't really much of an elevation - still, if you have a point of running services on unprivileged accounts you might want to pause to think about this.
