Connecting to a PIServer with a domain user

Hello Petter,

I hope you will forgive me , I have flagged Roger answer as correct instead because Connecting to a PI Data Archive explains very well the several scenarios and is a useful resource for the question: Connecting to a PIServer with a domain user

, especially:

// Get the PIServers collection for the current user and default PIServer.
 PIServer myPIServer = new PIServers().["SERVER_NAME"];

 // Simple connect with current windows user
 myPIServer.Connect();
 myPIServer.Disconnect();

// Connect and display a credential prompt dialog if current user login fails.
myPIServer.Connect(true, null);

Hello Petter,

No problem.

That being said, a credentials prompt won't work for us, as most of our software runs as services on servers that will ideally go months between each time someone logs into them. This means that the application should be able to restart and connect automatically.

This has normally been solved with explicit logins with username/password specified in the App.config and read into a NetworkCredentials object, but we're running into a situation where we can't do explicit logins because of the client's security requirements. The idea was to add domain to the config and put it into the NetworkCredentials object as described above, but since that showed up in the PI Message Logs as failed explicit logins I started digging further.

Yeah, that's the plan, and hopefully it will work.

I got confused by the claims that it should work with credentials when it turns out there's a difference between how PIServer and PISystem treat connections with credentials. I guess Roger's reply should be unmarked as correct since his solution doesn't apply after all, right?

Thanks for all your help!

Hello Petter,

I would recommend to use a service account for this purpose.  This does not require any line of code, you just need to give the needed access to the Service user.

And your service simply connect using:

--

Could that work for your scenario?

Hello Petter,

I removed the correct answer and flagged the question as assumed answered.
