Tips & Tricks:

The system updates the user profile with the information that the connection is no longer a persistent one if you pass this constant as <dwFlags>

private const int CONNECT_UPDATE_PROFILE = 0x1;

Sample Code:

[DllImport("mpr.dll")]
public static extern int WNetCancelConnection2(string lpName, Int32 dwFlags, bool fForce);
private const int CONNECT_UPDATE_PROFILE = 0x1;
private const int NO_ERROR = 0;

int result=WNetCancelConnection2("Y:", CONNECT_UPDATE_PROFILE, true);
if (result != NO_ERROR) {
//handle error
}
