Windows sevices and user permissions   

Hi all,
I'm developing a basic windows service.

The developing environment is VC++ 6 on Win XP - SP 3.

The service is being developed as a windows console application that
supports MFC.
It is of SERVICE_WIN32_OWN_PROCESS type and is configured as
SERVICE_AUTO_START.

I've specified NULL for the  lpServiceStartName parameter of the
CreateService()

function, implying a LocalSystem account for the service.

I can successfully install the service and in the services.msc
display, the logon

for the service is shown as "Local System".

I've logged into my system as a domain user and the network
administrator in my

organization reports that a domain user has local admin rights on my
system.

Now the issues are.

1. When I try to start the service from the services.msc, an error
message stating

"Error 5: Access denied" appears and the service fails to start. But
if I specify my

domain user name and pass word in the Log On tab of service properties
dialog, I can

sucessfully start service.

2. If I delete the service programatically using DeleteService, the
service does not

disappear from the services.msc window. Instead, it is shown as
disabled. If try to

start it from there, a message "Service marked for deletion" appears.
The service disappears from services.msc only if I restart the system.

Meanwhile, I can very well start or stop other services which have
Local system

logon.

a. Could anybody tell me what causes the above issues in my service?
Is it a issue

with my permission level?
b. Could anybody tell me how to debug the startup of a window service?
If I try to

debug from VC++ 6 IDE, the StartServiceCtrlDispatcher function fails
with

ERROR_FAILED_SERVICE_CONTROLLER_CONNECT error.

Thanks in advance.
Shaji.

RE: Windows sevices and user permissions   

I think the problem is that your service doesn't have a name with which you 
could manipulate (start / stop). Since your service is running 
(auto-started), you cannot delete it until next restart - and that's exactly 
what you see.

In the past I used SoftICE for service (and device driver) debugging, but 
you can also use Kernel Debugger - although for that you will need a SECOND 
computer connected to your test computer.
