Looking for a little help and I haven't found one that works with my situation. We have SCCM 2012 running and I am learning on the fly. I have a number of device collections setup based on AD groups. In the past when I moved a PC into an AD group the corresponding device collection would update. However today, the device collections have stopped updating in SCCM, in fact two new computers we added to the domain don't show up anywhere in SCCM right now. I've looked at the colleval.log, but it looks normal. I've rebooted the SCCM server as well and the collections still aren't updating. Both the site status and the component status are green across the board. I've checked replication across our DC's and that looks normal as well. Can someone help point me in the right direction? I'm willing to post log files; just let me know which one(s). Thanks in advance!
