You have two servers named Server1 and Server2 that run Windows Server 2012 R2. Server1 and Server2 are
part of a workgroup.
On Server1, you add Server2 to Server Manager.
When you attempt to connect to Server2 from Server Manager, you receive the following error message:
“Credentials not valid.”
You need to ensure that you can manage Server2 from Server1 using Server Manager on Server1.
What should you do?
A.
On Server 1, run the Set-NetFirewallRule cmdlet.
B.
On Server 1, run the Set-Item cmdlet.
C.
On Server 2, install the Remote Server Administration Tools (RSAT).
D.

Wrong, correct answer is B)
Remote computers aren’t automatically trusted for remote management on a managing server (as they are in a shared domain environment).
This is the only issue that is always present when the managing server running Server Manager and the server being targeted in Server Manager are not members of the same Active Directory domain.
To fix this problem, you need to configure the server running Server Manager to add the target server to its TrustedHosts list for remote management. To add the first server to the list, type the following at an elevated Windows PowerShell prompt:
Set-Item wsman:\localhost\Client\TrustedHosts TargetServer
