Hi everyone
I've got a strange one here. A workstation I noticed that wasn't scanned since 6 months (WinXP SP3, ZCM 10.3.1).
When I check the ZAA windows, it says Last Scanned i.e. today, Last Upload June 2.
I've found several errors 'Cannot start second instance of collector' in the local colw32.log.

However, the workstation gets rebooted daily and I can't find another instance of colw32.exe running in TaskManager.
How can I resolve this? I can't tell how many clients are affected. However, I've got almost 300 clients (15%) that haven't been scanned in the last 180 days...
