The Network application was designed to be a small utility that can enable / disable network connections and connect / disconnect dialup / ADSL / VPN connections. It requires admin rights so therefore it must be run with Encrypted RunAs.
The Syntax is:
For Network Connections
network.exe enable NamedConnection (blank for Local Area Connection)
network.exe disable NamedConnection (blank for Local Area Connection)
network.exe toggle NamedConnection (blank for Local Area Connection)
For Dialup/ADSL/VPN
network.exe connect DialUpConnectionName
network.exe disconnect DialUpconnectionName
network.exe toggledialup DialUpconnectionName
