I have a file server on my local network, then a server at a colocation, both Windows 2000 Server. I would like to allow my webserver to read/write to the file server on my LAN. Is there a reasonable solution via IIS 5, .NET through a web service, or some other sound solution?

I do have a VPN/Firewall between my LAN and WAN, maybe just a VPN Tunnel? Not sure about performance though.

Any thoughts would be helpful.

Thanks.
