Easy powershell function to resolve SIDs to SamAccountNames

Powershell function:

Function f-sid {
param ( [Parameter(Mandatory=$true)][String]$Sid)
$objSID = New-Object System.Security.Principal.SecurityIdentifier($Sid)
Try {
($objSID.Translate( [System.Security.Principal.NTAccount])).value
}
Catch {
Write-host “`nCouldn’t find any entry matching SID : $Sid” -foregroundcolor cyan
}
}


To use it:

> f-sid [yourSID]

if you have a list of SIDs in a txt file SIDs.txt

> get-content SIDs.txt | % { f-sid $_ }
