PSremoting failing on remote machines

Dear All,

I am facing some issues in terms of PSremoting.
On the Windows Server R2 with PowerShell version 4.0 I  have run the fallowing command:

PS C:\Users\lp73779> winrm quickconfig
WinRM service is already running on this machine.
WinRM is already set up for remote management on this computer.

Just to be sure I also run

Enable-PSRemoting -force

The inbound rules have been created on the firewall and are active.

I did

Enable-PSRemoting -force

on the Windows client with PowerShell version 4.0 and I get following output:

WinRM is already set up to receive requests on this computer.
Set-WSManQuickConfig : <f:WSManFault xmlns:f="http://schemas.microsoft.com/wbem/wsman/1/wsmanfault" Code="2"

Both ports 5985 for domain and private profiles on the Windows 7 machine are opened.
When I try to run Test-WSMan I got the fallowing error:

Test-WSMan : <f:WSManFault xmlns:f="http://schemas.microsoft.com/wbem/wsman/1/wsmanfault" Code="2150859023"

Can someone please advise what am I doing wrong or help out with the possible solution?

thanks in advance.
