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

    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?

    @Andrew Stipdonk

    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.
