Remote Desktop connection from Mac to Windows Server 2008 R2 fails

    Question

  • I have a Windows Server 2008 R2 box that is part of an active directory domain.  

    When I try to Remote Desktop to it from a Mac, and using a domain account, it fails.  I get an Event 4625 in the Security logs (shown below).  I also get an Event ID 56 with a source of TermDD.  I have decoded the Binary data, and tracked it down to a STATUS_TRUSTED_RELATIONSHIP_ERROR.  

    I can log into a non-domain account from the Mac to the same box without any issues. 

    I can log into the domain account from a Windows 7 VM (not part of the domain) without any issues.

     

    EventID 4625 message:

    An account failed to log on.

     

    Subject:

    Security ID: NULL SID

    Account Name: -

    Account Domain: -

    Logon ID: 0x0

    Account For Which Logon Failed:

    Security ID: NULL SID

    Account Name: <MyUserName>

    Account Domain: <MyDomain>

     

    Failure Information:

    Failure Reason: An Error occured during Logon.

    Sub Status: 0x0

  • Hi,

     

    Please changing the remote desktop setting on the target Remote Desktop Server to allow connections from computer running any version of Remote Desktop (less secure) to see whether the issue still exists.

     

    Please refer to the following article from Apple:

    Mac OS X: Cannot authenticate when Active Directory includes Windows 2008 Servers

  • We tried changing the settings and it still does not work.

    We just updated our Windows server to 2008 and now can not use Mac RDC.

    Please help.

    I have made that change on all my Windows 2008 and 2008R2 servers and I still get "The remote computer is not allowing connections from the Mac." - I do have a Windows 2003 domain controller that I can connect to via RDP on my Mac without any issues.  (I don't want to have to RDP to the 2003 DC and then RDP to a 2008 server.)

    I am using OS X Mountain Lion (10.8.2) and Office 2001 w/ SP2 installed.

    Anyone have any fixes for this issue?
