Changing or Adding ldap attibutes

Hi Everyone

I need to add several Ldap atributes to numerous computer accounts in Active Directory

I have this script but it only adds detail to one computer account. I need to read computer accounts from file

Script as follows:-

Set objComputer = GetObject ("LDAP://CN=ibook04,ou=A4 Apple Computers,ou=Classroom PCs,DC=churchdown,DC=gloucs,DC=sch,DC=uk")
objComputer.Put "description", "Art-A4"
objComputer.SetInfo

Any pointers would be appreciated :o)
