Hello
Since a short time I have the problem, that I can't connect to other computers in my network with WinRM, but only if I use the FQDN.
When I use only the computer name without the DNS suffix then it works.
The problem occurred on Windows 10 and also Windows Server 2019.
This is the error message if I use the FQDN:
Enter-PSSession: Processing data for a remote command failed with the following error message: The WinRM client received an HTTP bad request status (400), but the remote service did not include any other information about the cause of the failure. For more information, see the about_Remote_Troubleshooting Help topic.
I have also a strange behavior if I open for example the Hyper-V Snap-In and try to connect to another computer with Hyper-V. Then I see this message:
The object contained a value in property "Started" that is not valid.
Does anyone have any idea what causes this strange behavior?
DNS resolution is working fine, without FQDN and with.
Thanks for help.
