Hi, I have a peculiar issue where on the local machine where Mailbox, Client, and Hub roles are installed, I cannot connect to the Exchange server via EMC or Exchange PowerShell when I specify the local machine's FQDN. For example, the following command works fine and I can connect to the exchange server properly: $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://server/PowerShell/ -Authentication Kerberos HOWEVER, if I use FQDN, for example: $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://server.domain.com/PowerShell/ -Authentication Kerberos I get the following error: $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://server.domain.com/PowerShell/ -Authentication Kerberos I get the following error: [server.domain.com] Connecting to remote server failed with the following error message : WinRM cannot process the request. The following error occured while using Kerberos authentication: The network path was not found. 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 user names, but not local user names. -The Service Principal 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 Viewer for events related to authentication. -Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use HTTPS 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. For more information, see the about_Remote_Troubleshooting Help topic. + CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException + FullyQualifiedErrorId : PSSessionOpenFailed How do I fix this? thanks! -sul.
