A pure PowerShell option, assuming you have PowerShell 2.0 on your TeamBuild machine, is to use a background job. Start-Job allows you to specify the credentials of another account to perform the work.

$cred = Get-Credential
$job = Start-Job -ScriptBlock { ls c:\windows\system32 -r *.sys } -Cred $cred
Wait-Job $job
Receive-Job $job
