copy-item With Alternate Credentials

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..?

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

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

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

[Here][1] is a post where someone got it to work. It looks like it requires a registry change.

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.

This [question][1] addresses a very related issue that may help [using network shares in powershell][2].

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

This is an old question but I'm just updating it for future finders.

**PowerShell v3 now supports using the -Credential parameter for filesystem operations.**

Hope this helps others searching for the same solution.

I know that [PowerShell 3 supports this out of the box][1] now, but for the record, if you're stuck on PowerShell 2, you basically have to either use the legacy `net use` command (as suggested by several others), or [the Impersonation module that I wrote][2] awhile back specifically to address this.

Bringing this back from the dead again. I got around a similar credentials problem by wrapping the .ps1 in a batch file and doing the Win7, Shift + r.Click RunAs. If you wanted to, you can also use PsExec thus:

psexec.exe /accepteula /h /u user /p pwd cmd /c "echo. | powershell.exe -File script.ps1"
