I'm in the process of trying to install Exchange 2016 in my environment. I had a functioning Exchange 2013 installation and it crashed hard after attempting to apply a CU; it was dead, and not easily repairable, not a critical server. I manually removed the exchange server from ADUC and ADSI. I ran the PrepareSchems, PrepaerAD, and PrepareDomain all successful.
I started the installation and I receive the following error during the installation and I can't seem to figure out where to investigate. I have the setup logs if that's any help, but the error during installation.
Error:The following error was generated when "$error.Clear();
if ( ($server -eq $null) -and ($RoleIsDatacenter -ne $true) )
{
Update-RmsSharedIdentity -ServerName $RoleNetBIOSName
