How to remotely eject cd drive

[Antblue]

I have tried to gain remote access through computer management, yet it says that "You do not have access rights to Logical Disk Manager on 'COMPUTERNAME'." I have also tried to gain access with psexec,but the error message Access is denied to 'computername'. I have tried with powershell to get this error message "The
 WinRM client cannot process the request. If the authentication scheme is different from
 Kerberos, or if the client computer is not joined to a domain, then HTTPS transport mus
t be used or the destination machine must be added to the TrustedHosts configuration set
ting. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts l
ist might not be authenticated. You can get more information about that by running the f
ollowing command: winrm help config. For more information, see the about_Remote_Troubles
hooting Help topic." Any help on this would be appreciated.
