Some computers randomly changing group membership in WSUS with server side targeting.
Posted on 2014-07-31
We have a server 2003 based WSUS server that is doing strange things.
I have configured it to use Server Side targeting. I have noticed it doing a strange thing that appears to be random and infrequent enough. I have configured a few groups or containers for computers in the WSUS console, of which currently only one is getting automatic approvals pointed at it. The other containers are not being targeted (for now) and as such will not get updates. All of these groups contain some number of computers that I have assigned to them.
Now the strange part. Some of the computers change container membership by themselves, jumping from one to the other, while other or even the same computers disappear entirely and then come back. Also note, that I am entirely aware and cognizant of that "filter computers by" filter and ensure I have it set to any followed by a refresh.
Does anyone have any ideas why some computers disappear and or change container membership?
