If you are working at the sockets level (as opposed to http or ftp or a webservice, etc) for the upload then programmatically select the local VPN EndPoint with the Socket.Bind method for the upload. Just explicitly call Bind before Connect.

This has much more to with the network and routing config of the machine then anything you would (or could) do programmatically - especially from .NET code. What you want is that packets to the IP address of the server you want to upload to are always routed through the VPN interface. You'll want to search the Win2K docs, or other resources for information about routing (eg. use the "route print" command to see how packets are being routed through interfaces).

I have a dual-NIC Win2K Server that needs to grab data from the local network (1st NIC) and then upload it to a server through a VPN (2nd NIC).
The problem I am facing is that the upload doesn't always work when I run
it
- it appears that the program is looking at the local connection and not finding the VPN site, so it errors out. Sometimes I can get it to work
the
second or third time, but not always. If I disable the Local connection first, the upload to the VPN works fine, but then I have to re-enable the Local connection to continue.
Is there a way to either: 1) Force the Upload to use the VPN connection, or 2) Disable and re-enable Network Connections programmatically?
The EndPoint information I have found in MSDN seems like the way to go,
but
it appears to only return the value rather than allow me a chance to set
it.
I have not been able to figure out the right search terms to find the answers, but am still looking...
