For some unknown reason, certain Windows systems (such as XP SP2) have a problem where the TAP-Win32 adapter installs fine but then doesn't show up in the network connections panel. I've made a patch (in 2.0-test29) that tries to work around such cases. Up until now, OpenVPN would not sense a TAP adapter unless it was in the network connections panel, or more accurately in the registry data structures which contain the data which is displayed by the network connections panel. On Windows, the registry info for network adapters is actually separate from the registry info displayed by the network connections panel. So a network adapter could be correctly installed, but still not show up in the network connections panel. In such cases, OpenVPN would not be able to sense the TAP adapter. In 2.0-test29, OpenVPN will no longer depend on a TAP adapter existing in the network connections control panel registry list. If the TAP adapter is missing from the network connections list, it will still show up with the --show-adapters flag, and it can still be referenced by --dev-node, using the adapter's GUID as it's --dev-node name. So now, --dev-node supports either the friendly, renameable name from the network connections panel (as it's always done), or the low-level GUID which uniquely identifies each adapter on the system, including those which are hidden from the network connections panel. If you use a GUID with --dev-node, make sure to enclose it in braces.
