I read the DOC saying if we stop publishing a sccm site server info to AD the objects in AD are not automatically removed. They need to be manaully removed. I want to know how can I manually remove these objects? Can I just open ADUC and browse to system management container and delete two objects associated with this site server? (one MP folder one site obj) Thanks,

Yes, just delete all object from the System Management container.Kent Agerlund | My blogs: http://blog.coretech.dk/author/kea/ and http://scug.dk/ | Twitter @Agerlund | Linkedin: /kentagerlund

Yes, all the information that ConfigMgr will publish is stored under the System Management container. You can use ADUC and clean the two objects associated with your site server. Regards, Madan
