I have 2 domains that are untrusted.
DomainA has my single primary site with following roles installed on two servers: MP, DP, SUP. I now have a request to put SCCM in DomainB for purpose of Software Updates. The docs say I can install site roles onto untrusted forest
server, but I am limited to only one active SUP in the whole site. So my question is, in order to get a SUP in the second untrusted forest, can I create a secondary site in DomainA, with no roles installed, then setup server in Domain B and install the
necessary roles (MP, DP, SUP)?
