Sounds like you have set up the AD sync at the root level "My Organization", this would make your manual created group and systemobjects disppear at each sync. To solve this set up the AD sync on a first level group instead that is on the same level as your "Repository Servers" group.
- AD Synced group
- Repository Servers
thanks for the tip!
Sounds logical indeed to do it that way ;-)
Indeed, you need to set up your Sync in a level below 'My Organisation' & then the manual groups will remain,
Had exactly the same issue here but ended up with all of my desktops (100K+) sitting in lost and found as they were populated manually.
Ho Hum- all sorted now though
