powershell - 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

I have encountered this recently, and in the most recent versions of Powershell there is a new BitsTransfer Module, which allows file transfers using BITS, and supports the use of the -Credential parameter.

The following sample shows how to use the BitsTransfer module to copy a file from a network share to a local machine, using a specified PSCredential object.

Import-Module bitstransfer
$cred = Get-Credential
$sourcePath = \serverexamplefile.txt
$destPath = C:LocalDestination
Start-BitsTransfer -Source $sourcePath -Destination $destPath -Credential $cred

Another way to handle this is using the standard "net use" command. This command, however, does not support a "securestring" password, so after obtaining the credential object, you have to get a decrypted version of the password to pass to the "net use" command.

$cred = Get-Credential
$networkCred = $cred.GetNetworkCredential()
net use \serverexample $networkCred.Password /USER:$networkCred.UserName
Copy-Item \serverexamplefile.txt C:LocalDestination
