Hello,
you are converting the sid byte[] to a string (using .ToString). This will end up with something like "System.Byte[]". You must extract the byte[] from the entry and pass it to the SecurityIdentifier constructor.
Best regards,

As shown in my code, that's what I'm trying to do but it's not working.
SecurityIdentifier si = new
SecurityIdentifier(dsReport.Tables["AdComputers"].Rows[y][0].ToString());
I'm getting the following exception error at run time:
System.ArgumentException:Value was invalid. Parameter name:sddlForm at
System.Security.principal.SecurityIdentifier..ctor(String sddlForm)

Thanks.

Hello,
if you are using .NET 2.0, you can pass the byte[] you get from the
objectSid property to a SecurityIdentifier class.
Otherwise, you have at least these options:
1) (easy one) Call the Win32 function ConvertSidToStringSid.
2) (more difficult, but more flexibility) Call the Win32 DsCrackNames
function
Best regards,
