Sitecore 9 XP1 Topology - Error on UpdateSolrSchema step while calling PopulatedManagedSchema.aspx

Question

I'm installing Sitecore 9 XP1 Topology, and everything was going well until Content Management step where I received this error

Install-SitecoreConfiguration : Error requesting https://sitecore9-cm/sitecore/admin/PopulateManagedSchema.aspx?indexes=all: The remote server returned an error: (500) Internal Server Error. At line:1 char:1 + Install-SitecoreConfiguration -Path .\sitecore-XP1-cm.json + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Install-SitecoreConfiguration

I've found a blog talking about the same error but in his case the log said "Login Failed for user" and mine does not mention anything (at least I didn't find)

When I browse to https://sitecore9-cm I receive the following error

Answer 2

I had the similar error while installing Sitecore 9 Update 1. I figured out that it is due to missing ASP installation. I installed the ASP .Net 3.5 and 4.7 and gave a try. It worked for me. Please check the below image and give it a try. It might solve the issue for you.

Answer 3

We faced the similar error while installing Sitecore 9 Update 2, because I was configuring on the new machine with first time .Net/Sitecore installation. The problem was due to missing ASP component (ASP, ASP.net 3.5 and ASP.net 4.7) Go to > Control Panel\Programs\Programs and Features Click > Turn Window Features on or off Navigate To > Internet Information Services > World Wide Web Services > Application development features

ASP

Asp.net 3.5

Asp.net 4.7

And make sure, all three above option should be checked, if not checked it and click ok. Hope, it will resolve the issue.
