Old Server name

I built a 2012 r2 server.  I named the server with an underscore in the name as requested by the application developer, e.g. "server_name".

Later we discovered that this was causing an issue with the server, so we changed the name to, e.g. "server-name".

However, when we load software on the server, it finds the server name with the underscore instead of the server name with the hyphen.

Where is it getting this?  DNS shows the right name, the server shows the right name.

You stated: "..when we load software.."
Do you mean any and all software being installed or only the software that forced the server name change?

Have you rebooted the server after changing the Server name?
The name change will not fully apply until a reboot is completed, causing the symptoms you describe.

The server has been restarted many times.  We have an application that utilizes a web-service for collecting data.  When we installed the web-service, it completed the installation, but would error out when we ran the application.  In troubleshooting, we discovered that the web-service was calling the old server name, not the new server name.  This was not something we configured during the install, and I don't see a way to change it now.

So what we are attempting to do is find out where it pulled the old server name from during the install.  If we can correct that, we should be able to uninstall and re install the web-service and hopefully that will solve the problem.

Some quick thoughts:

Is the App and web service on the same local server?

Without knowing anything about your environment or software, I wonder if your Web Service is calling the IP of the old/ new server and DNS returned the wrong name?

Perhaps a Host file was manually edited in the past and now needs to be updated?

Is the service using a named pipe or a custom Database instance? A database can use a machine's name for a named instance as a connection.
