Are Separate Mid Servers required when discovering multiple domains that don't have a trust setup?

[robertgeen]

Let's say we have Domain A in which the Mid server is installed on and we want to discover 2 other domains (Domain B and C) but Domain B and C don't have a trust with Domain A. Does this require a Mid Server in Domain B and Domain C in order to discover the servers on those domains? I know that discovery uses power shell to do impersonation for launching WMI queries but I am unsure of whether or not Domain B and C would be accessible from the Mid Server due to their being no trust relationship in place. Let me know what everyone thinks.

Can you please explain how we can create multiple midserver instances? with this method only one mid server would be sufficient to discover multiple domain(having no trust between)? How?

Any solution on the above issue? We are facing a similar issue with the trust setup. 
Created a separate credential for each domain with local admin and able to ping / telnet from one domain to another domain. We are able to do remote call also but the credential test is failing and win / powershell command is also failing from one domain (mid server) to another domain. 

The difference is both the domains are not trusted. Is it required to discover multiple domain using a single mid server? 

Could you please help us with your suggestions? 

Thanks in advance!
