[PATCH] Windows VPN connection script fix to set default domain for DNS

[kylej61782 at gmail.com (Kyle Johnson)]

In most work environments it's important to set the default domain for
DNS requests, so this addition to the connection script achieves that.
I should note that this is accomplished via WMI instead of using NETSH
since NETSH strangely doesn't have the capability to actually set this
parameter.  It's also available via PowerShell, but I'm fairly certain
this doesn't work in earlier versions of Windows, so the WMI solution
ought to be more universal.
