We have been battling an issue with a client for about 4 months now. PCs are randomly getting hung on shutdown at different points in the week with no rhyme or reason. We have scoured the event log and can see nothing that would cause this. We cant recreate the issue because if on those same PCs we can reboot and itll reboot as normal. Also at random times during the day users will be unable to browse the C: or mapped drives without manually putting in the directory (ie C:\windows\) Any direction on what we could use/logsto see what is causing the shutdown hangs and random slow browsing folders?
