Create a SecurityIdentifier object and translate into a NTAccount:

    1:  $objSID = New-Object System.Security.Principal.SecurityIdentifier 

    1:     ("S-1-5-21-3496554487-1900509739-3140548133-500")

    2:  $objUser = $objSID.Translate( [System.Security.Principal.NTAccount])

    I have a list of SID's. How can i import a file and get the result? As the above example is for single SID.

    If the account has been deleted the translate will simply fail You could use a try catch construction and return the SID in that case for example Try {  $User = $objSID.Translate( [System.Security.Principal.NTAccount]).Value } Catch {  $User = $objSID.Value } $user
