Seems like AD Sync is not configured correctly in EPO.
Check the configuration and share the screenshot of the AD Sync Configuration Page.
the settings seem correct, at least the same as the other containers which fucntion as expected.
another thing which is bothering me, is that it will pick up nodes from other containers and add them to this one, as if they were the ones from this domain (they have the same netbios names). for example, (made up names and ips) currently server3.domain2 ip 18.104.22.168 is not in epo and is unmanaged, no mcafee software installed. server3.domain1 ip 22.214.171.124 is in epo is maanged and is in container domain1. when i synchronize, server3.domain1 is placed in the container for domain2 and is tagged domain2. happens for a couple of servers.
thanks! (sorry for late reply, i didnt seem to get a notification in my inbox about the reply)
had to select " Move systems from their current System Tree location to the synchronized group" and not "Leave systems in their current System Tree location only " in sync settings (even though this seemed to work in other groups)
