exchange 2010 sp1+sharepoint foundation emc error

Arkadaşlar merhaba

Server 2008 std r2 üzerinde exchange 2010 sp1 kurulu exchange role u var. bu servera sharepoint 2010 foundation kurdum.Bu kurulumdan sonra exchange management console açılışında aşağıdaki hatayı vermekte.

WinRM iis exstension kuruldu. iis virtual directory powershell silip tekrar oluşturdum fakat değişiklik yok.

 the attempt to connect to http://exch2010.contoso.local/powershell using "Kerberos" authentication failed:

Connecting to remote server failed with the following error message: WinRM cannot proccess the request.The following error occured while using Kerberos authentication.There are currently no logon servers avaliable to service the logon request.

Possible  causes are :

-The user name or password specified are invalid

-Kerberos is used when no authentication method and no user name are specified.

-Kerberos accepts domain usernames, but local user name.

-The services Prinicipal Name(SPN) for the remote computer name and port does not exist.

-The client and remote computers are in different domains and there is no trust between the two domains.

After checking for the above issues try the following :

-Check the Event wiever for events releated to authentication.

-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use HTTP Transport.

Note that computers in the TrustedHosts list might not be authenticated.

-For more information about WinRM configuration, run the following command: winrm help config.
