SCOM 2016,Unable to resolve the user xxx associated with the user role. Error code 1332

Problem

===========
Unable to resolve the user xxx associated with the user role. Error code 1332

Cause

=========
Normally – when you have a trust with a remote account domain, and you want to add users from the rote domain to SCOM, things go perfectly.

However, if the user account in the remote domain uses a different UPN name than the SAM account name – the SCOM UI block’s it.

  

Solution

===========

Use SCOM PowerShell to add these users to the role:

$Role = Get-SCOMUserRole -Name "MSFT TEST"
$Role | Set-SCOMUserRole -User ($Role.Users + "MSFT\jimmytest")

After applying update KB4025336 to our WSUS servers clients are no longer able to communicate with WSUS.

Cause
========
the virtual directories were throwing internal server error 500's for the WSUS

Error 2912 (0x80070534) happened when a host was added to VMM.

Cause

=========
The error occurred after the AD service account was renamed, and then the account mismatches with that in VMM registry.

Resolution
==============

1. Login to VMM server machine, and check the below registry:

     HKLM\Software\Microsoft\Microsoft System Center Virtual Machine manager Server\Setup\VMMerviceAccount

Please make note of the value.

2. Compare it with the account in AD side, and make sure they are matching.
