Dim $UserName, $DomainName, $Password $UserName = "administrator" $DomainName = "**********" $Password = "********" RunAsSet ( $UserName, $DomainName, $Password ) $val = FileCopy ("P:\installs\ebrary\ebrary_xp.exe", "C:\", 1) $val = RunWait("C:\ebrary_xp.exe", "C:\", @SW_MAXIMIZE) The P drive is located on one of the servers in the domain. All users can read and copy from it, but cannot write to it. The administrator is an admin account on the domain. Sorry for the tone of my last post. It was the end of a longm annoying day! Thanks in advance.
