Hi I have been tasked with setting up our current SCCM environment to manage clients in another forest prior to us migrating them into our forest sometime next year. I've checked other posts in the forum and have a good idea of what I need to do but just wanted to clarify that I am going in the correct direction. Forest 1 contains our SCCM infrastructure and forest 2 is where the clients are that I need to manage. There will be no SCCM servers in forest 2. Forest 2 trusts forest 1 and SCCM is in mixed mode. I already have an SLP configured in forest 1 as we manage workgroup computers and I can resolve the SCCM boxes from clients in forest 2. If I have understood what I have read correctly I can treat the clients in forest 2 in the same way that I would workgroup computers in forest 1 i.e. specify SMSSLP in the installation properties of the SCCM client. My questions are: 1. Is this correct? 2. I'm assuming that the boundaries for clients in forest 2 can be assigned as I would for clients in forest 1? 3. Will I be able to use OSD to deploy OS to clients in forest 2? 4. Is there anything that I have missed? Do I need to give the SCCM computer accounts any access is forest 2? Thanks in advance.

Hi SRR1012, 1) Well, sort of. 2) Depends on how you assign boundaries in forest 1. For instance, you can use subnets as boundaries. 3) Yes 4) No, you do not need to give the SCCM computer accounts any access in forest 2. 5) SCCM is not limited to Active Directory. This is in fact a key issue. For the SCCM system to work you do not need any trusts. SCCM can manage computers in domains that are not trusted. You just have to specify a network access account. Think of clients in other domains as clients in a workgroup.Kind regards Tim Nilimaa IT Consultant at Mindgrape (Sweden) Please remember to mark this answer as helpful if it helped you.

Hi Tim Thanks for the reply. I probably should have specified that the boundaries would be subnets. Network access account is already there so should be good to go. Thanks for the clarification.
