Ae galera, eu achei um sistema de upload sem componentes, e funcionou perfeitamente no meu PSW.

bom são duas páginas, uma com os formulários para fazer o upload e outra com o script para carregar o arquivo para a pasta desejada, aí vai:

página: formulario.asp

' Change the value of the variable below to the pathname
' of a directory with write permissions, for example "C:\Inetpub\wwwroot"
Dim uploadsDirVar
uploadsDirVar = "D:\pasta\codigos e tutoriais\Códigos\ASP\Sistema de Upload\"
' ****************************************************

' Note: this file uploadTester.asp is just an example to demonstrate
' the capabilities of the freeASPUpload.asp class. There are no plans
' to add any new features to uploadTester.asp itself. Feel free to add
' your own code. If you are building a content management system, you
' may also want to consider this script: http://www.webfilebrowser.com/
