Windows 10 Active Directory Admin Client Error

gtjr92 · Apr 9, 2021

Windows 10 Build 1904 1

I have an issue using Active Directory Admin Center on windows 10. Anytime I open it, it just says active directory admin center must close due to unknown error. Never had this till recently. This only happens on one windows 10 pc. I can go to another windows pc and AD Admin works fine. Here is event viewer log

Application: dsac.exeFramework Version: v4.0.30319Description: The process was terminated due to an unhandled exception.Exception Info: System.ComponentModel.Win32ExceptionException Info: System.Security.Authentication.InvalidCredentialException at System.Net.Security.NegoState.ProcessReceivedBlob(Byte[], System.Net.LazyAsyncResult) at System.Net.Security.NegoState.StartSendBlob(Byte[], System.Net.LazyAsyncResult) at System.Net.Security.NegoState.StartSendBlob(Byte[], System.Net.LazyAsyncResult) at System.Net.Security.NegoState.ProcessAuthentication(System.Net.LazyAsyncResult) at System.Net.Security.NegotiateStream.AuthenticateAsClient(System.Net.NetworkCredential, System.String, System.Net.Security.ProtectionLevel, System.Security.Principal.TokenImpersonationLevel) at System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider+WindowsStreamSecurityUpgradeInitia tor.OnInitiateUpgrade(System.IO.Stream, System.ServiceModel.Security.SecurityMessageProperty ByRef)Exception Info: System.ServiceModel.Security.SecurityNegotiationException

Also I have found at the same time this issue started now when using network application or accessing a network share I get prompted for my username and password. When I enter my credentials everything works fine for those. I did not have to login to these before. I only get this issue on one pc. If I use another pc with AD Admin it works fine.

I assume this is an AD joined device?

If so run the following powershell command. It should return true
Test-ComputerSecureChannel

I ran it it did return True

Is there a HRESULT returned in the error log? You definitely have some kind of configuration issue and it's not able to establish a secure session.
