Re: running a service/driver/application upon startup

Would it be possible for you to drop a debug services.exe and debug nk.exe
into your image? Hopefully these wouldn't put it over the maximum size.
I'm hoping if you can crank up full debugzones on these then they can tell
you where we're going wrong in this various scenarios.

Not being able to load Telnetd is a red herring. If telnetd detects it's
not being loaded under device.exe or services.exe, its DllEntry() returns
FALSE and that gets you ERROR_DLL_INIT_FAILED.
