All of my machines show this STEngine error when the machine has been logged off and is left alone for the evening. After a successful log in, the error stops for the day. For instance, my machine had this error occur every few minutes from 5:25 PM (the time I logged off my machine for the evening) all the way to 8:15 this morning. After I logged into the machine, the error stopped. Is there a reason this is occuring? Thank you.

Error is as follows:

Source: STEngine
Event ID: 49
TDI Thread Exception at number 2164

The exception number is consistant at 2164.

Just curious what is happening here and if there is reason for concern. All the clients are communicating and are receiving the correct policy.
