5 years ago I was working at Continental Airlines learning MSI with Windows Installer 2.0. One of the biggest pain points was troubleshooting why services wouldn’t start. Some programs just had horrible COM/ATL issues relating to COM extraction not working and /regsvr having race problems.
One of the more aggravating scenarios was for a program called Gate Reader that had a windows service with a dependency on a active directory service account.
Inevitably one of two things would go wrong: Either someone had locked the account out ( and no installs would work for up to the next 15 minutes ) or the service account had never been assigned the SeServiceLogonRight priv on the machine being installed to.
Now we can talk about eliminating the dependency by eliminating the service account but at the end of the day development typically doesn’t give a flying brown mass about deployment/operational problems.
So it’s the later that always irritated me. Why in the world is it that Windows Installer has columns in the ServiceInstall table for describing a service account but when it creates the service it doesnt’ grant the SeServiceLogonRight priviledge?
A quick hop over to Services and type in the username and password gets you a dialog that says the account has been granted logon as service.
I know I’m not the only one to have this problem because there are many threads where setup developers suggest using the not-quite-redistributable NTRIGHTS.EXE to get around the problem.
So anyways, it’s now 2008 and I’m running MSI 4.5 and sure enough, it’s still a problem. Ugh. The good thing is I’ve since learned C# ( Gatereader was a .NET 1.1 application at the time ) and I’ve got DTF at my disposal. This allows me to make use of a project that was available on CodeProject some five years ago that at the time meant nothing to me:
LsaUtility.SetRight( session.CustomActionData[“ServiceAccount”], “SeServiceLogonRight” );
Nice, thank you DTF! Now my real implementation is datadriven using the ServiceInstall table but I wanted to show how simple the problem is to solve with just one line of C# thanks to a freely available class file and DTF.
So while some things stay the same, some things actually do get better.
