I've installed a windows service in a windows 2003 server. It start manually succesfully but if I run it from another application return an error.
The running code is this:
Dim myController As ServiceController
myController = New ServiceController("WinSUpdateProdDate")
If Not myController.Status = ServiceControllerStatus.Running Then myController.Start()

...returned error is (in italian debug...)
? ex.Message
"Impossibile avviare il servizio WinSUpdateProdDate sul computer '.'."
? ex.InnerException.ToString
"System.ComponentModel.Win32Exception (0x80004005): Accesso negato"

In connection properties of the service default option is selected: local user account.
What can I do to solve?

There are two ways you can fix this.  You can elevate the privileges of the code calling the servicecontroller, or you can give rights to the user to manage the service.

Method 1 will bring up a User Access Control prompt.  Method 2 should be transparent.

Method 1, either run program as administrator (right click and "run as"--should bring up the UAC prompt)  or add a manifest with the elevation request, which will cause the UAC prompt on start up.

To add a manifest, open project properties and click "View Windows Settings"  in VS2010 or add "Application Manifest File" to your project in VS2008.  

change  <requestedExecutionLevel level="asInvoker" uiAccess="false" /> to
 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

Method 2
I've never done this, but I believe this would be the best way.  Sounds like it's a little tricky:
Set permissions on a specific service (Windows)

Your indications are very useful. Thank you.
I've tried both. Onestly method two is not very clear. First is more simple.
Starting application UAC message ask for confirmation and I can't change UAC level.
Searching on the internet I've found this utility: subinacl.exe (component of Resource Kit) You can download from Microsoft web site.
I've changed permission for the service using this command:
SUBINACL /SERVICE <service name> /GRANT=<user name>=TO
