RE: Cannot Control a Service - Access Denied - WHAT?

OnSessionChange has something to do with Terminal Services.

My question is what user do you have this service running under? From your
error it sounds like your tying to access some database from your service.

Subject: [padnug] Cannot Control a Service - Access Denied - WHAT?

Hello all, hope you were able to stay cool this weekend.  I figure the only
reason to come to work today is for the free air conditioning!

 

On to business:

 

I have written a service that I now need to write some sort of
administration program for.  In my service, I have created an event log
which for now I am using as my debugger.  I have overridden all of the
standard stuff: OnStart, OnStop, OnContinue, OnCustomCommand, OnPause,
OnShutDown, OnSessionChange <-- Don't know what this is.

 

In my Admin Project I have a simple form that, using a Service Controller
can Stop, Start, Pause and Resume the service, but when I try to send the
service a custom command I get the error: Cannot control DBAuthentication
service on computer '.'.  The exception details are
below:

 

System.InvalidOperationException was unhandled

  Message="Cannot control DBAuthentication service on computer '.'."

  Source="System.ServiceProcess"

  StackTrace:

My question(s) are:

 

Is there something wrong with my service or with my Admin Program?

How can I fix this?

 

Thanks in advance,
