I have always have an issue with clients (servers and desktops) getting stuck at downloading updates and never progressing even after days. I have read numerous posts here and on technet about this issue and I am still not able to fix it. I want to think that because its so widespread that its something with boundaries but I'm not sure.
I have 6 boundaries for 6 different physical locations and they were all added from ad sites not subnets. I have 3 boundary groups which contain the majority of the boundaries. (some offices have closed but the ad sites still exist for now).
Which logs would help me determine if its a boundary or an update / update group issue?
