In the good old days it was possible to deploy the NwClient patches by
simply applying the .inf file via an application object (rundll32
setupapi,InstallHinfSection DefaultInstall 128 ....). This seems no
longer beeing possible on XP for security reasons (you are getting a
unsigned or incorrectly signed file error).

Does anyone have an idea how to stop XP from that ugly behavor?
Thank's for your help.
