Strange behavior of the Domain Administrator Account

Question

I have a problem since a few days. My domain administrator account can't open the Exchange Powershell anymore, I get the message "WinRM can't process the request". I don't have this problem with another administrator account, and I don't have this problem when I connect with the domain administrator account from another server.

When I use Powershell, I get the message "Windows Needs Your [Domain] Current Credentials".
This message also appeared when I want to open the Users and Computers console on my domain controller.

I recreated the profile on the server by renaming its original folder, then deleting the Regedit entries, but nothing helps.

I am on a Windows Server 2008R2 and Exchange 2010.

Thank you!

Hi @Sagaroth ,

Does your full error message look something like this?

Connecting to remote server failed with the following error message: The WinRM client cannot process the request. It cannot determine the content type of the HTTP response from the destination computer. The content type is absent or invalid. For more information, see the about_Remote_Troubleshooting Help topic.

If so, you could refer to the troubleshooting in the link below :

Troubleshooting Exchange 2010 Management Tools startup issues - Microsoft Community Hub

Alternatively, you can use EMTshooter to provide you with information based on detected errors or problems:

In addition, because Exchange 2010 reached its end of support on October 13, 2020, Microsoft no longer provides:
• Technical support for problems that may occur.
• Bug fixes for issues that may impact the stability and usability of the server.
• Security fixes for vulnerabilities that may make the server vulnerable to security breaches.
• Time zone updates.
Your installation of Exchange 2010 will continue to run after this date. But because of the changes listed above, we strongly recommend that you migrate from Exchange 2010 as soon as possible.
For more information about ending support for Exchange 2010, you can refer to this link: Exchange 2010 end of support roadmap - Microsoft 365 Enterprise | Microsoft Learn
Thank you for your understanding!

You need to add the host to your TrustedHosts list. You can do so with a command such as:
Powershell

set-item wsman:\localhost\client\trustedhosts -Concatenate -value 'hostname'
