Try to use WMI - Windows Management Instrumentation to disable network connections.

WMI is visual basic / scripting friendly COM-technology based API and doesn't provide greate abilities though. But hope it helps

One possibility would be to use IpReleaseAddress to cut the connection, and IpRenewAddress to re-start it. Another possibility would be to use SetIfEntry to disable/enable the network interface.

A rather brute force way on windows if you're getting your address via DHCP is to just make a call to ipconfig /release and ipconfig /renew when you want your access back.
