Running SCCM current branch single site - I have followed all the troubleshooting steps suggested in every forum post and Microsoft tech papers. Backed up my schema, then extended schema (while publishing from site server to AD was disabled) and did this with a Schema Admin account, verified that the Site server computer account has Full control over the Systems Management container, that the SMS-Site- object is currently located in the Systems Management container, etc... I still am getting this error. I am only about a month and a half into this SCCM learning experience so I know I am probably missing something and therefore, ANY help is appreciated.
