Hi Team, After establishing central and primary site server hierachy, all the collections in central site server gets locked. By default data flow would be from central site to primary site In mycase what would happen? In my previous configuration only from primary site server collections gets locked but now vice verse pls help..

Collections are replicated down and never up, so that should not happen at all.Torsten Meringer | http://www.mssccmfaq.de

What needs to be done to fix this issue

What have you done before? Did you just add a new parent to the existing primary site? Or were there other actions involved?Torsten Meringer | http://www.mssccmfaq.de

Can you check that you didn't add a parent site ti the central site. I have seen that before. If that's not the case, you'll need to concact Microsoft PSS.Kent Agerlund | My blogs: http://blog.coretech.dk/author/kea/ and http://scug.dk/ | Twitter @Agerlund | Linkedin: /kentagerlund

I have 3 servers in my lab enviroment. The below steps I have followed 1. Created standard sender address 2. add respective hostname in SMS_SiteSystemToSiteServerConnection_sitecode & SMS_SiteToSiteConnection_sitecode 3. Changeed the site settings ... report to parent site

You could try running a site reset. Follow Kent's instructions if that does not help.Torsten Meringer | http://www.mssccmfaq.de
