primarily two methods - bagging and random subspace method. Suppose we decide to have S number of trees in our forest then we first create S datasets of "same size as original" created from random resampling of data in T with-replacement (n times for each dataset). This will result in {T1, T2, ... TS} datasets. Each of these is called a bootstrap dataset. Due out of bag estimation breiman to "with-replacement" every dataset Ti can have duplicate data records and Ti can be missing several data records from original datasets. This is called Bagging. Now, RF creates S trees and uses m (=sqrt(M) or =floor(lnM+1)) random subfeatures out of M possible features to create any tree. This is called random subspace method. So for each Ti bootstrap dataset you create a tree Ki. If you want to classify some input data D = {x1, x2, ..., xM} you let it pass through each tree and produce S outputs (one for each tree) which can be denoted by Y = {y1, y2, ..., ys}. Final prediction is a majority vote on this set. Out-of-bag error:After creating the classifiers (S trees), for each (Xi,yi) in the original training set i.e. T, select all Tk which does not include (Xi,yi). This subset, pay attention, is a set of boostrap datasets which does not contain a particular record from the original dataset. This set is called out-of-bag examples. There are n such subsets (one for each data record in original dataset T). OOB classifier is the aggregation of votes ONLY over Tk such t

I've been googling it with out https://www.quora.com/What-is-the-out-of-bag-error-in-Random-Forests any luck yet. I only have one SCCM server in my organisation, so it's not due to miscommunicating with other SCCM servers or anything(the managment controller and the out of band service point). LP The out of band service point failed to discover with https://social.technet.microsoft.com/Forums/systemcenter/en-US/296cd011-171f-4278-916c-364b89cb6382/out-of-band-error-message?forum=configmgrgeneral error 0x 0. Possible cause: This condition can be caused by transient network connectivity errors. The credential used to connect management controller is invalid. The management controllers are in unavailable status. Solution: Verify network connectivity is functional between the out of band service point and the management controller. Verify that the credential used to connect the management controller is valid. It may be necessary to reset the management controller to factory mode and provision it again.

But there are requirements for using each feature. The requirements are not all automatically installed by ConfigMgr.
