When you use a dial-up or Virtual Private Networking (VPN) connection to reach a remote network with non-Windows servers, you must be sure that the remote servers’ protocols are carried over the connection. In this section, I’ll refer to dial-up connections, but whatever I say applies to VPN connections as well.
The AppleTalk protocol is not transmitted over a Windows dial-up connection. You can reach Macintosh file servers only if the remote network uses the file and print services for Macintosh gateway service on a Windows .NET, 2000 or NT server, or, if the Macintosh computers use a Windows-compatible TCP/IP-based protocol.
