Error opening remote console after Configuration Manger in place OS upgrade

Quick post about issues connecting to site with remote console after upgrading the server OS from Windows 2008 R2 to Windows Server 2012 R2

After the upgrade all remote console were unable to connect to the site

console-error

After reviewing the SMSAdminUI.log  on one of the remote devices, there were access denied errors.

\r\nSystem.Management.ManagementException\r\nAccess denied \r\n   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
:System.Management.ManagementException\r\nAccess denied \r\n   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)

I granted one user local admin rights to the SCCM server, which was hosting the SMS Provider and the console access was restored.

I reviewed the DCOM permissions which were fine, however, the WMI permissions for the SMS Admins group were missing!

I check the WMI permissions using wmimgmt.msc and added the required permissions

I removed the local admin permissions and tested again. Console access was working again

More detail

In order to access a local or remote SMS Administrator console, users must be members of the SMS Admins local group. The SMS Admins group is explicitly granted Enable Account and Remote Enable on the Root\SMS namespace. The SMS Admins group provides its members with access to the SMS Provider, through WMI. Add Users to the SMS Admins group when they need to access the SMS Administrator console, but do not have to be Local Administrators
