Hello, We used the option "Domain Tree in an existing forest" when we run DCPromo and now we have 2 Domain Trees. My question is: does anyone knows if SCCM could work properly in such AD&DNS implementation? Many thanks,

Hi, Sure ConfigMgr. will work in that environment.Kent Agerlund | http://scug.dk/members/Agerlund/default.aspx | The Danish community for System Center products

Hi, It's fully supported for SCCM running in a multi-domain environment. For efficient management, a multi-site hierarchy can be taken into consideration: Configuration Manager Multiple Site Planning and Deployment http://technet.microsoft.com/en-us/library/bb693854.aspxPlease 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.
