Server Manager crashes on startup, faulting module ntdll.dll

Question

Getting this error on all domain-connected servers when using a domain administrator account.

Log Name:      Application
Source:        Application Error

Here's what we know:

• All servers are less than 60 days old and all steps have been completed for all servers
• Only occurs with domain administrator accounts, even newly-created domain admin accounts which are fresh. Local administrator accounts can access Server Manager just fine.
• Installed all updates, up to KB4577668.
• Forced updates/repairs for .NET 3 and .NET 4, installed .NET 4.5 and .NET 4.7.2.
• Ran .NET Verification. Verification succeeded for 4.7.0, 4.7.1, and 4.7.2.
• Executed SFC, no issues found. Ran DISM, no issues found.
• Cleared MMC cache in %userprofile%\AppData\Roaming\Microsoft\MMC

I'm out of ideas, does anyone have a suggestion?

The only conclusion I can reach is that this might be related to AD simply because that is the only common denominator. That being said, I have not found any reason based on AD why this might be happening.

Hi Iskandar,

Try following methods to narrow down this issue:

1. Open command prompt as administrator and run gpresult /h report.html to check the configuration of the administrator as well as the computer for any special configurations that can cause this problem.
2. Reinstall the DLL
   1. Type cmd in the search box, and then right click Command prompt select Run as Administrator.
   2. Type this in command prompt:
      regsvr32.exe /u ntdll.dll and press Enter key (this will uninstall the file)
      regsvr32.exe ntdll.dll and press Enter key (this will reinstall the file).

Let us know how it goes.

Best regards,

Molly

Regsvr32 sends the error:
The module "ntdll.dll" ws loaded but the entry point DLLUnregisterServer was not found.

Make sure that "ntdll.dll" is a valid DLL or OCX file and then try again  

Looking into that, this error seems common because ntdll is not a registerable dll

I've attached the report to this post, only changed the domain name for privacy reasons.
