Found that issue only with this WebSite:

Default Web Site 1 Started %SystemDrive%\inetpub\wwwroot http :80: net.tcp 808: net.msmq localhost msmq.formatname localhost net.pipe *

I am having a similar problem with my web server. I have tried both WebSites.

ConvertTo-Dockerfile -local -OutputPath I:\i2d2\test -Artifact IIS -ArtifactParam test -verbose

I'm using the version 1.8.5 and the problem still there. I have a scenario where the Default Web Site has 2 applications (beta and alpha) under it, and I want to extract only one of those applications (in that case, beta). Here's command run and the log:

ConvertTo-Dockerfile -Verbose -Local -OutputPath c:\i2d2\iis -Artifact IIS -ArtifactParam "Default Web Site/beta"

Still having the same issue. I don't know if the fix ever got merged because, I see the problem raised as an issue previously. Below is my -verbose output:
