I have begun getting ts hangs on multiple servers that had run for a quite awhile without issue. The problem is the system just becomes unresponsive to certain tasks.
For instance if I am logged in as admin and users state system is frozen, I can still function within my session as can some others. However, if I open taskmgr and click on users tabs it locks up. None of the usual tools quser, qwinsta will return any data. tasklist and taskkill also hang. I even built a brand new ts2008rs ts on a 2016 physical box and the issue has crept in. I do have 3 in another location and they are not experiencing the issue. I have also run av and other scans to no avail.
Any thoughts?
