Dial-up Connections

If you have multiple private networks or ISPs to connect to using dial-up, you can make copies of an existing dial-up connection and rename and modify each copy as desired. Just right-click on the connection and select Create Copy. You can also copy direct and VPN connections.

Specifying a high value for "Idle time before hanging up" for a dial-up connection doesn't guarantee that the connection won't be terminated earlier by the remote access server, which typically has its own disconnect timer configured on it.

Direct Computer Connections

Direct computer connections can also work with modems, ISDN adapters, infrared ports, and other devices.

Incoming Connections

If you try to create a second incoming connection on a machine, it overwrites the existing connection.

Incoming connections can interfere with receiving incoming faxes from the Fax Service. The solution is to make sure you use a modem that supports adaptive answer.

Local Area Connections

On a multihomed computer with multiple network adapters installed, rename each local area connection to reflect the subnet to which it is connected.

If the system has more than one network adapter, make sure you disable any that aren't being used.

You can enable or disable a local area connection as desired in different hardware profiles for laptop computers that can't automatically detect the presence of a connection.

VPN Connection

WS2003, XP, W2K, NT 4.0, Windows 98, and Windows 95 client computers can establish VPN connections with a WS2003 remote access server, but note that:

• All of these clients have built-in support for PPTP except Windows 95, which requires the installation of the optional Windows Dial-Up Network 1.3 Performance & Security Upgrade component.

• Only WS2003, W2K, and XP support L2TP.

• NT 3.5x doesn't support VPN connectivity.

You can also create a VPN connection across a LAN between a VPN client and remote access server, which is becoming a popular way of making your local network secure against sniffing by insiders.
