SCCM Caching AD info

[Schikitar]

Hi all,

 

This might sound a bit weird but I'm having some problems with creating collections in SCCM 2012 R2. It's like it's not pulling live data from AD but instead some sort of older/cached data?? For example, we moved all our Grade 7 machines from the Grade 7 OU to the Grade 8 OU and so on with all the year levels. When I recheck membership some weird things start happening such as the collection for Grade 8 shows 9 members and the collection for Grade 9 shows 195 members (should be 94 and 95 respectively). I've left this for a couple weeks (got busy!) and it's still doing the same thing, it looks like it's referencing AD information from a previous point in time and it's not reflecting how AD currently looks.

 

Any thoughts on this? We just started our new school year today, so I need my collections to be working so the right year levels are getting the right software via Software Center.

 

Cheers!
