New-PSDrive fails remotely

kevsor1 — Thu, 15 Jul 2010 05:00:00 GMT

Hi,

When I try to map a drive locally on "Client1", it works fine with this command:

New-PSDrive U -PSProvider FileSystem -root \\Server1\C$

but when I try it remotely, it fails ($cred is a previously created credential):

Invoke-Command -ComputerName "Client1" -Credential $cred -ScriptBlock {
new-psdrive U -PSProvider FileSystem -root \\KJS-Manage\C$
}

The error message is:

Drive root "\\Server1\C$" does not exist or it's not a folder.
+ CategoryInfo : ReadError: (U:PSDriveInfo) [New-PSDrive], IOException
+ FullyQualifiedErrorId : DriveRootError,Microsoft.PowerShell.Commands.NewPSDriveCommand

I thought maybe I have to use CredSSP, so I enabled delegating credentials in the GPO:

"Computer Configuration\Policies\Administrative Templates\System\Credentials Delegation\Allow Delegating Fresh Credentials"

and added the domain to the servers list:

"WSMAN/*.mydomain.net"

Then I enabled WSMan:

(on Client1): Enable-WSManCredSSP -Role Server

(on server I'm remoting from): Enable-WSManCredSSP -Role Client -DelegateComputer "*.mydomain.net"

Then I retry the remote command with authentication:

Invoke-Command -ComputerName "Client1" -Credential $cred -Authentication credssp -ScriptBlock {
new-psdrive U -PSProvider FileSystem -root \\KJS-Manage\C$
}

And now I get this huge error stating that it can't connect to the remote server because WinRM client cannot process request... computer doesn't allow delegation of user credentials to target computer... and it tells me to edit the group policy setting that I mentioned earlier.

What am I missing? If new-psdrive doesn't work remotely, and I can't use credssp remotely, how do I remotely setup a psdrive? All I want to do is have 1 script cause several servers copy test results on their local drives to a common file share, but so far I'm having no luck!

Thanks for any help/suggestions!
