Debugging Topshelf service that won't run under restrictive account

I have a Windows service written using Topshelf. I'm trying to configure it to run using a Windows account with restricted privileges rather than using LocalSystem. That's also necessary as I'd like to connect to a database using integrated authentication.

The service works when run as LocalSystem (albeit with a database connection string containing credentials) and running the console application as my limited account (using runas) also works.

However, when I try to start the service the service control manager times out waiting for a response:

The service did not respond to the start or control request in a timely fashion.

I also get the following in the Application Popup event log:

Application Error : The exception unknown software exception (0xc06d007e) occurred in the application at location 0x77e4bef7.

The first thing that the application does is writes to a log file but it doesn't reach that when I start the service. The logging works if I run via the console.

Any suggestions what I might be missing or what I might try next?

This problem seems to be related to the server (a domain controller) rather than TopShelf. A service built with the .NET service component also exhibits the same behaviour.

The service runs successfully on a different machine (in the same domain).

Unfortunately this doesn't help diagnose the problem but gives me an acceptable workaround.

Check the MSDN article Debugging windows services which describes how you debug windows services.

I've just started seeing this on a few of my services written in .net 2.0. They'll start fine when the server boots, but if I were to restart them throughout the day, they would not start, and give this error message.

They currently ran under a domain account which has admin rights on the box, but for kicks, I switched it to Local System, and the service started normally. I stopped it, changed it back to the domain account (reentering the password), and it started normally again as expected.

Don't know if this counts as a 'fix' so much, but that's what worked for me.
