I have managed to put myself in a bad position. I accidently deleted my AD integrated group within my SEP manager which contained almost all of my workstations(approx. 16k). So now all of these machines are showing up in the Default Group. I started the "Import Organizational Unit or Container" process but that takes approx. 50min to get to a list of my AD groups. Then when I choose the AD Group I want to integrate it seemed to be running however I was away from my session for an extended period of time and when I got back my Symantec console session had closed due to the 1hr timeout I had set on SEPM console sessions.
At this point I am wondering if that initial import is still working in the background.....or did it cancel out when my session closed? I'm leaning towards cancelled out when my session closed.
What I'm wondering though for my next try is if I can choose the "Run in Background" option during the Import and leave it go.
Hardest part about this trial and error is the amount of time I need to wait in between tries. Considering how large my environment is how long would you expect an import like this to take? Has anyone else ever done a large import like this?
