PowerShell Remoting giving Access is Denied error

Question

I am trying to use PowerShell Remoting to check some disk sizes from a Server in a remote domain  but the commands I am running are failing to work   The situation is like this    Source Server is in Domain A Destination Server is in Domain B There is no trust in place between these domains   The Server in Domain B is running Exchange 2010  and I can run Exchange 2010 Specific commands against it from Server A using this command    Session   New-PSSession -ConfigurationName Microsoft Exchange    ConnectionUri  ConnectionURI -Credential  Credentials -Authentication Basic Import-PSSession  Session   The problem is that I can t run any non Exchange commands against this server using this session  if I try then it says that it can t understand the commands  I ve checked and running Get-Command with Invoke-Command and the -Session variable set to my established session only returns Exchange commands   So I thought i d try to use Invoke-Command and the relevant ComputerName  Authentication type and Credentials  but this is failing   Invoke-Command -ScriptBlock  Get-Service  -ComputerName  Servername destination com  -Credential  Credentials -Authentication  Basic    This is the error    servername destination com  Connecting to remote server failed with the following error message   The WinRM client can not process the request  The authentication mechanism requested by the client is not supported by the server or unencry pted traffic is disabled in the service configuration  Verify the unencrypted traffic setting in the service configurat ion or specify one of the authentication mechanisms supported by the server   To use Kerberos  specify the computer nam e as the remote destination  Also verify that the client computer and the destination computer are joined to a domain  To use Basic  specify the computer name as the remote destination  specify Basic authentication and provide user name a nd password  Possible authentication mechanisms reported by server      Negotiate Kerberos For more information  see th e about Remote Troubleshooting Help topic        CategoryInfo            OpenError          PSRemotingTransportException       FullyQualifiedErrorId   PSSessionStateBroken   So I go into the WSMAN config on the Target server and set the relevant settings for allowing Basic Auth and an unencrypted connection   cd WSMan  localhost Service Set-Item AllowUnencrypted  True cd   Auth Set-Item Basic  True   I also have added the Destination server into the Trusted Hosts of the Source domain server   cd WSMan  localhost Client Set-Item TrustedHosts servername destination com   After doing so  the error changes  but it s not very helpful   PS WSMan  localhost Client gt  Invoke-Command -ScriptBlock  Get-Service  -ComputerName  servername destination com  -Creden tial  Credentials -Authentication  Basic   servername destination com  Connecting to remote server failed with the following error message   Access is denied  Fo r more information  see the about Remote Troubleshooting Help topic    CategoryInfo            OpenError          PSRemotingTransportException   FullyQualifiedErrorId   PSSessionStateBroken   I have also tried using Domain Admin credentials  via -Credential  Get-Credential   but this is failing with the same problem   The user I am trying to use is a member of the local Admins users on the server in question  so the permissions should already be set on the PSSessionConfiguration containers   I would love any further pointers with this  I would just use WMI but it s not enabled through the firewalls at the moment

Had similar problems recently  Would suggest you carefully check if the user you re connecting with has proper authorizations on the remote machine   You can review permissions using the following command   Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft PowerShell   Found this tip here  updated link  thanks  unbob      https   devblogs microsoft com scripting configure-remote-security-settings-for-windows-powershell   It fixed it for me

Running the command prompt or Powershell ISE as an administrator fixed this for me
