you mean you are kicking off scans of pcs from the server tasks or remote console I guess..
tbh ive never noticed a difference, I didnt think that the calculating estimate came into it on task related scans (the timings shown in the logs never suggested it was running) I know that when i remote console and run the scan task manually from the remote machines console this is an issue though, and you have to click the button again.
I assume you have tried this via an epo scheduled task and the option is still there then?
It gets quite confusing... my test results: (Always the same machine with the same ePo-scheduled task)
1. scan running silent, without opening the progress window => 4:30 to 5:00 hours 2. with opened progress window and stopped calculating estimate => about 3:45 hours 3. with opened progress window and calculating estimate => 1:40 to 1:50 hours :confused:
Yes, you can turn it off, but via a switch on the scan32.exe. Add \noestimate to the scan32.exe to skip that. However, I don't recommend it since during the estimating, it's building a baseline of so you don't go over your CPU utilization that you assigned to it. You skip this, you might go over the assigned CPU utilization that was set for it.
