We have an application that runs in Windows Server 2008 R2 SP1. It is a job launched from the Task Scheduler which runs TCC.EXE (v15 x64) sets up some environment variables and launches a PERL script.
The issue we are seeing is that the event log is getting polluted with warnings about event ID 1903. These events are triggered by MS security update ME896358 or security update ME890175.
This warning only occurs when the job is launched from the Task Scheduler and told to runas a specific user. It appears it is the Scheduler itself (or Windows in general,in response to the Scheduler) logging an error when trying to unload the Windows user-profile used in/by the Scheduled Task from memory. This is reinforced by the fact that if the user in question is already logged in (and stays that way), the error apparently doesn't happen.
Apparently, the application TightVNC had this issue and they changed something in later releases to stop it from happening.
We tried these settings from TechNet to no avail:
Looking through the hhctrl.ocx file, I see some other interesting registry values, but I don't know what they do.
Any ideas?
