Mapping to Network Share

I have a question about using a system.io streamreader. I'm successfully able to map to a local file. But I would like to map to network share but the syntax below does not work. Do you not use server.mappath or is there another command to map to a file on a network share.
Below is my code. Any help would be appreciated.

 currFileName = Server.MapPath("\\myMachine1\\SPI-Share\\Reboot_wkly_rpt.txt")
 fileNameTemp = Server.MapPath("\\myMachine1\\SPI-Share")
 fso = CreateObject("Scripting.FileSystemObject")
 mainfile=fso.GetFile(currFilename)
 mainfile.Copy (fileNameTemp)

If you are using a network path, you don't need to call "Server.MapPath".
