How to add WSUS/DP in an another domain

Question

Hi,

We have 2 domain

• Domain A
• Domain B

Domain A has fully working SCCM setup (Up to date)

In Domain A we are using SCCM to build/Application/Packages and push updates

Domain A is fully setup as HTTPS

Now I need to patch and build new machine in Domain B

What do I need to do to patch/build machine in Domain B

Will I need an DP/WSUS in Domain B?

Will I need an MP in Domain B?

How will the cert work in domain B as my Domain A is fully HTTPS?

What accounts need to setup/created on Domain B?

Where do I need to add these account?

Have you looked at the blog post by Jason Sandy that covers details on cross domain support involving ConfigMgr? It is a bit old, but still holds up. https://home.memftw.com/configmgrsccm-domains-forests-trusts-oh/

In my personal opinion, it will come down to ConfigMgr features & number of clients that you need to support in other domains. Accordingly you will then need to decide on the sizing of the ConfigMgr infra to introduce the relevant number of site roles. Once you have that sorted, then you can then start working on setting up the pre-requisites like certificates etc.
