copy-item With Alternate Credentials...

Question

I'm using the CTP of powershell v2. I have a script written that needs to go out to various network shares in our dmz and copy some files. However, the issue I have is that evidently powershell's cmdlets such as copy-item, test-path, etc do not support alternate credentials...

Anyone have a suggestion on how best to accomplish my task..?

Answer 1

that evidently powershell's cmdlets such as copy-item, test-path, etc do not support alternate credentials...

It looks like they do here, copy-item certainly includes a -Credential parameter.

PS C:\> gcm -syn copy-item
Copy-Item [-Path] <String[]> [[-Destination] <String>] [-Container] [-Force] [-Filter <String>] [-I
nclude <String[]>] [-Exclude <String[]>] [-Recurse] [-PassThru] [-Credential <PSCredential>] [...]

Answer 2

You should be able to pass whatever credentials you want to the -Credential parameter. So something like:

$cred = Get-Credential

[Enter the credentials]

Copy-Item -Path $from -Destination $to -Credential $cred

Answer 3

Here is a post where someone got it to work. It looks like it requires a registry change.

Answer 4

I would try to map a drive to the remote system (using 'net use' or WshNetwork.MapNetworkDrive, both methods support credentials) and then use copy-item.

Answer 5

This question addresses a very related issue that may help using network shares in powershell.

Answer 6

Since PowerShell doesn't support "-Credential" usage via many of the cmdlets (very annoying), and mapping a network drive via WMI proved to be very unreliable in PS, I found pre-caching the user credentials via a net use command to work quite well:

# cache credentials for our network path
net use \\server\C$ $password /USER:$username

Any operation that uses \\server\C$ in the path seems to work using the *-item cmdlets.

You can also delete the share when you're done:

net use \\server\C$ /delete
