I was reviewing/deleting videos on Netcamstudio client running on same machine as server and I saw those Even log entries (multiple time always in couple) :
My guess (I am developper) is that there is some unsynchronized activity between the physicial deletion of Videos+Thumbnails and the Gallery viewer and internal Database (if there is one), the gallery still have in memory a list of thumnails that do not exist anymore physically so it produce the error until the Gallery dabatase has been refreshed, and the 401 error may be in reality a 404 “not found” or may be a lock what set by a process that blocked other process access and the resilting erreor has been transleted into 401 ?
As I have activated the glog fie it’s easier to look into and what is strange is that I get ANonymous and Local Admin users connecting locally ? with Anonymous (just for one request) I guess
