We run Groupwise. Most of our servers are 2008R2. I have done the requisites of powershell 2.0 and configuring winrm as the template states. What is weird is that some are working and others are getting the below error. Also any that are on 2012 servers are working fine too. So I'm not sure what is different on the 2008R2 installs that some are working and others aren't. Any help on how to troubleshoot?
Output: ==============================================
Message: Connection error: Exception calling "DownloadString" with "1" argument(s): "Unable to connect to the remote server"
