If we have a collection of 70 systems and don't want them get advertisements or any windows updates ect. from SCCM. Would simply blocking them be the best way to prevent and SCCM communicator until we are ready for them to communicate again and then simply unblock them?

Just don't advertise the update package on that collection.Zulqarnain Ali | MCTS, MCSA | Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Put them in a 1 min long maint windows and make sure you use maint windows for everything. Also exclude members of that collection from all other collections using a subselect query. John Marcum | http://myitforum.com/cs2/blogs/jmarcum/|

Create a GPO and stop the SMS Agent Host Service, that way the client is not working.Kent Agerlund | My blogs: http://blog.coretech.dk/author/kea/ and http://scug.dk/ | Twitter @Agerlund | Linkedin: /kentagerlund

While Kents suggestion will definately work I feel like that's just putting a band-aid on a gaping wound. If configured properly you should never have any concerns what-so-ever that a client will run a package that you do not intend for it to run. If that's not something you can accomplish you need to bring in a consultant or someone with more experience. SCCM is very powerful. The last thing you want to do is accidently send out an OSD package to all computers in the company or something horrible like that. With proper collections, maintenance windows, properly configured advertisements etc this should never be a concern. John Marcum | http://myitforum.com/cs2/blogs/jmarcum/|

Hi, You don't need to block or disable your client for just don't let them receive any software or updates. Propery software distribution / software update / OSD settings are needed and keep this collection out of any of the target collection and make this collection exculded in all your distribtion's target collection. Thanks
