Re: How to remote start/stop services using windows API?

Hi Jeffrey,

Thanks for your reply:)

Logonuser seems only works only when local machine and remote machine have
same usename/password pair. If my application running on machine A under user
"aaaa", the service running on machine B, it must be stopped using user
"bbbb", and this user doesn't exist on machine A. How could I use Logonuser
to stop the service in machine B?

BTW, is there any limitations if machine A is in a domain and machine B is
NOT in domain, and vice versa?

Thanks,

Hi Tom,

Thanks for your feedback.

Do you mean that the account you are calling OpenSCManager does not have
enough right to connect remote SCM? So you use the username/password pair
of valid account on remote machine to call WNetAddConnetion2. I assume so.

NetUseAdd and WNetAddConnection2 will both call into the client redirector
for SMB file server connections for windows file server connections, so you
can run into the session conflict with existing connections. Moreover,
there can be any number of legitimate reasons for connections to already
exist to the target server.

The recommended solution is using LogonUser(LOGON32_LOGON_NEW_CREDENTIALS),
impersonate the resultant token, then perform the remote operations. This
will ensure you'll use the specified credentials for remote authenticated
operations, regardless of the transport. So it helps you to avoid the
session re-use issue.

Hope this helps.

Best regards,
Jeffrey Tan
