Cannot validate the logon user account against the domain controller

I am getting the error "Cannot validate the logon user account against the domain controller." when trying to install the Enterprise Console 5.1 on a Windows 2008 R2 server that is in our DMZ.  Even though it is in the DMZ, it is still a domain member and I have logged into it as a domain user that is also a Domain Administrator.  My guess is a port needs to be opened but which one if I can already login as a domain user?

  • That error code is the user not found error but I am logged in as a domain user that has domain admin rights.  I have tried logging using both the domain\username format and the UPN format and get the same error when running the Enterprise Console 5.1 setup.  I have checked that the TCP/IP settings are set to the correct internal DNS servers that the domain uses and they are resolving correctly.
