The applications that I support are all on older servers. New servers are being set up with Windows Server 2019 so that the applications can be deployed here allowing the older servers (Windows Server 2012 R2) to be decommissioned. I am following the exact same deployment steps (using deployment batch files that have been used for many years) on the new server that I do on the older servers but am getting the following messages that I do not get when I deploy to the older servers:
Info: error

Any thoughts?

This may be caused by incorrect location of your application, you can try to add application as a virtual directory in the IIS.
The other web app servers that this is deployed to do not have the issue nor do they have a virtual directory listed for the app in IIS. Having said that I still created the virtual directory on the new 2019 Server but the issue still persists. It appears that the web site is created and is accessible but the error messaging still appears.
Can you post your website configuration information? And the web.config file, what is the difference compared to the website on the older server.
The web code and deployment method are the same for all the servers (old and new). The old servers are Windows 2012 R2 and 2016 while the new server is 2019. I will see about the web.config shortly.
I cannot post the web.config file but I do not see anything in it that would cause the issue. Is there anything in particular you are looking for?

Apparently the issue is that the path needs to be changed. I have always been using /LM/W3SVC/2/ROOT/ but now I need to use /LM/W3SVC/1/ROOT/. This resolves the errors.
Does anyone know what this number represents and why changing it makes a difference on the different servers?
This is the path in your project, we have no way of knowing what 1 and 2 represent, you can find the difference by looking for the path of this folder and comparing it.
