accessing Service Control Manager from a kernel driver

NTFSD
1

sorry, it was implicitly in my mind and I omitted to spell out “from a
kernel Driver” !

does anybody know whether I can access the Service Control Manager (SCM)
from kernel mode driver logic,
under NT4, to be able to start/stop a service which is cooperating with
my kernel mode driver ?

if so, what calls can I use ?

thanks,

Bob.

Hello,

AFAIK it is not possible. The user mode calls such as
OpenSCManager, OpenService residing in ADVAPI32.DLL
makes direct RPC call to services.exe process.

What you can do is, have some user mode process which
will do this job and have your driver communicate with
this program whenever it wants to start/stop services.
