>How can i get the user's name (login name) from Windows NT usign a Activex Control?

You can get this information by parsing the return from SYS(0) - the user name is on the right side of the # character in the string. You can use the Wscript.Network object from the WSH - it has a UserName property. There are also mechanisms available in the Win32 API to get any of several possible userids.
