Windows Service - Event Log

[pisquem]

I am building an windows service that is to be deployed on a windows
server 2003 and I want to have activity written to the event log, I
want its own log called ('CustomLog')

Below is what I have so far...its builds fine but when I go to start
the service i get the following error.

---------------------------
Services
---------------------------
The CWindowService service on Local Computer started and then stopped.
Some services stop automatically if they have no work to do, for
example, the Performance Logs and Alerts service.
---------------------------
OK
---------------------------
What am I doing wrong? Right after this code I have this line....and it
never had an issue.
EventLog.WriteE ntry("Refresh started successfully.") ;

//1. Create the source, if it does not already exist.
if (!EventLog.Sour ceExists("Custo mLog"))
{
EventLog.Create EventSource("Cu stomLog", "MyNewLog") ;
}
//2. Create an EventLog instance and assign its source.
EventLog myLog = new EventLog();
myLog.Source = "CustomLog" ;
//3. Write an informational entry to the event log.
myLog.WriteEntr y("Writing to event log.");

Without seeing more of the start code i couldn't say for sure,
however, when I was working with this recently I found that by having
evaluating code in my OnStart event I had a tendancy of recieving the
same error. What I would recommend you do is add a component timer to
the service(not a form timer) and put your code in the Elapsed event of
the timer. Then in your OnStart method you just activate the timer.

Hi,

You need to post more code, or more details at least.

Where are you running this?
What your onStart looks like?

Are you creating a new thread in the onStart ?

Usually what I do is in the onStart just create and Start a thread that is
the one who does the real thing. in this way the onStart returns
inmediately.

What credentials is the Service running under? It is possible that the
Service's account does not have the necessary permission to write to the
Event Log.

When i tried that (on a default windows 2003 installation) i experienced
a problem with access rights. If i remember well, i had to give the
'network' user access rights to the registry keys..

Check your service account, only admin accounts have the right to "create"
private logs. If your service run with restricted privileges (which is
good), you'll need to create the log from another program, not from within
your service.

What registry key's?
The "Network Service" account is a restricted service account with
sufficient privileges to write/read to/from the eventlog, if you elevate
it's privileges, you break what it was designed for.

What registry key's?

HKLM/System/CurrentControlS et/Services/Eventlog (or one of it's
children).

Yes, but why do you want your service to write to this key?
Only Administrators (and localsystem) are allowed to write to HKLM and
descendants, Service accounts are not supposed to write to HKLM. If you
really need your service to write to HKLM, you need to run as "localsyste m".
Again if you grant a non privileged account write access to HKLM, you
severely compromise your system's security.

Every Windows Service runs under a specific user account, which is assigned
to it, either by the developer when creating the installation for the
service, or by an administrator/authorized user via the Services snap-in.
So, there is no single user account under which all Windows Services run.
