I was looking for a scripted way to rename the tap network node to
make it easier for installing my clients.
Attached is the batch file I used to rename my network node. I still
have to answer yes to two questions but that is much easier to
instruct someone to do.
This was tested on Windows 7 it should work on older versions of
windows (with XP it should work even better) but I haven't tried it
yet.
Basically what this script does is as follows
it dumps the content of
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
and looks for the "TAP-Win32 Adapter V9" DriverDesc and matches it up
with its NetCfgInstanceId
It then creates a reg file that modifies the
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\[NetCfgInstanceId]\Connection\Name
registry entry to the name you have in the client.ovpn config file.
Could Microsoft have picked a more obscure naming convention?
