ServiceControlManager returns Error = 5 when Openservice Called

[TheMillionDollarMan]

Hi

I have created an application that is to be run as a service. When I try to create the service the ServiceControlManager returns Error = 5 when OpenSCManager is called.

This works on my machine no problem. However on another machine i get this error. How can I solve this problem.

Thanks

Try to test the return value against standard error codes for OpenSCManager (ERROR_ACCESS_DENIED,ERROR_DATABASE_DOES_NOT_EXIST, ERROR_INVALID_PARAMETER) and see which one of the above is returned.

Also, you can use GetLastError in conjunction with FormatMessage to get a brief description of the error.

Thanks B00gyeMan!
I found out that this is an "Access Denied" type error.

Do you know how I can give myself rights to enable acces to OpenSCManager?

I want to be able to create a service on a target machine.

Thanks

Only an administrator or power user cand give itself security rights.

It is not necessary a problem of security. Some application might have locked the database using LockServiceDatabase API. According to MSDN: "The LockServiceDatabase function requests ownership of the service control manager database lock. Only one process can own the lock at any given time."

If you are connecting to a remote database (that is, on a remote machine), you should be aware that "Only authenticated users are granted the SC_MANAGER_CONNECT, SC_MANAGER_ENUMERATE_SERVICE, and SC_MANAGER_QUERY_LOCK_STATUS access rights."

Also, only processes with Administrator privileges are able to open a database handle that can be used by the CreateService and LockServiceDatabase functions.

So, check if you are connecting as an authenticated user and also check your security rights.
