WinRS/WinRM kann nicht auf UNC-Pfad zugreifen ("Multi-Hop" mit CredSSP)

[t0mso]

Hallo,

ich hoffe ihr erlaubt mir, mein Anliegen auf Englisch zu beschreiben. Ich habe dieses nämlich gerade so einem englischsprachigem Freund geschildert. Gerne könnt ihr natürlich auf Deutsch antworten.

Ganz herzlichen Dank schonmal.

I am trying to send a WinRS command from clientX to server1, which inlcudes a UNC path reference to a shared folder on server2. I understood that therefore I need to perform credential delegation from clientX to server1 ("double-hop"). Both clientX and server1 actually have access to that shared folder on server2.

clientX -> server1 -> server2

I followed all available instructions regarding WinRM and CredSSP configurations, like this: [Multi-Hop Support in WinRM - Win32 apps and it appears to me that everything was set up as intended.

• hostname of clientX is 'clientX' (acquired from cmd command 'hostname')
• full computer name of clientX is 'clientX' (acquired from control panel > system)
• user domain of clientX is 'CLIENTX' (acquired from cmd command 'echo %userdomain%')
• hostname of server1 is 'server1' (acquired from cmd command 'hostname')
• full computer name of server1 is 'server1' (acquired from control panel > system)
• user domain of server1 is 'SERVER1' (acquired from cmd command 'echo %userdomain%')
• the unc path on server2 is \SERVER2\sharedF\test

on server1, I can successfully run the command:

dir \\SERVER2\sharedF\test

on clientX, I can aswell successfully run the command:

dir \\SERVER2\sharedF\test

on clientX, I can successfully run the command:

winrs.exe -r:http://SERVER1:5985 -u:adminOnserver1 -pass4server1 "dir c:"

on clientX, I fail to run the command:

winrs.exe -r:http://SERVER1:5985 -u:adminOnserver1 -pass4server1 "dir \\SERVER2\sharedF\test"

as I receive the error message "access is denied". And that is the problem.

on clientX, the power shell command

Get-WSManCredSSP

returns:

The machine is configured to allow delegating fresh credentials to the following target(s): wsman/SERVER1
This computer is not configured to receive credentials from a remote client computer.

on clientX, the cmd command

winrm get winrm/config

returns:

Any ideas?
