I know of a couple of ways to do this. One is to use interop calling
WNetCancelConnection2 (see links below) or you can use the WMI class
Win32_NetworkConnection and use the ConnectionState property to disconnected
to turn it off.

I hope this helps

Win32_NetworkConnection ConnectionState is read-only. You can't change it's
state.
Only thing you can do using WMI is unloading/loading the device driver for
you connection (exactly as the Control pannel Connections applet does when
disabling/enabling).

It's not clear what exactly you want to achieve.
Do you wan't to disconnect from a remote resource (a file share for
instance), or do you wan't to disconnect a client session from a shared
resource?
Or is it something else?

My error with the connection state. Thanks Willy.

You can still use interop to disconnect... that is if this what you are
looking for.

Good luck.

Brian,

I'm pretty sure the solution is in System.Management (WMI), but first we
have to know exactly what OP is looking for.

Who is Brian ?

What do you mean by "What OP looking for" ?

I couldn't do it with WMI. Do you have another idea ?
