I will verify all these settings tomorrow as soon as I get a chance (so busy!)... thank you for the info. I am pretty sure I configured the clients to point to our update server through our policy now, but we were previously using ESET MSP Utilities & LabTec (and whatever licensing goes with that), which we no longer use (I have since uninstalled ESET MSP Utilities). I have no clue how nod32 was installed on these client machines before i got assigned with this. Like I said most of them are working 100% fine no issues whatsoever just a few problematic machines. I will let you know how it goes, one way or the other. Honestly want to upgrade everything to the newest version eventually.. I just want to beat this problem first before I tackle the next task.
Thank You
