My current setup is: 2 domains: Win 2003 domain named A Win 2008 domain named B Two seperate forests, full trust between them. Sccm setup: Primary site server in domain A in location 2 Primary child server in domain B in location 1 Site systems have been published in both AD's with boundaries set to the right location IP ranges. So now I have a member server in domain B and location 2, when that server checks his AD for the site code it doesnt find it's boundary there because the Primary site server cant publish it in domain B, I am also not able to add these boundaries to the Primary child (option isnt there). How do I make this work, use an SLP or by some other method? Thanks in advance!

Found out that when installing the client and using SMSSLP="Primary site server" it can assign the site code automaticly even when the server is a member of domain B.
