Map a drive on your PC to //sabrina/c$
This only works with zip files or exe files. It won't work with .psm or .txt files.
You have to create a self-extracting zip file out of the files you want to send because the customer's server probably won't have winzip installed.
Put the self-extracting .exe file you want to send into this folder on sabrina: inetpub\wwwroot\mvsoftware\mvsoftware\download
Go to the customer's server via Remote Desktop
Start their Windows Explorer and key this into the address box:
http://www.mvsoftware.com/mvsoftware/mvsoftware/download/filename where filename is the the zip file you created
It will ask you to open or save the file, say save and put it in their where you need it on the customer's server.
